Chicken Hatching
Background Information
Some facts about chickens
A chicken is a bird. One of the features that differentiate it from most other birds is
that it has a comb and two wattles. The comb is the red appendage atop the head, and the
wattles are the two appendages under the chin. These are secondary sexual characteristics
and are much more prominent in the male. The comb is the basis of the Latin name or
classification of chickens. In Latin, gallus means comb, and the domestic chicken is Gallus
domesticus. The Red Jungle Fowl, ancestor of most domestic chickens, is Gallus bankiva.
There are eight recognized kinds of combs: single, rose, pea, cushion, buttercup,
strawberry, V-shaped, and silkie.
The chicken has two legs and two wings, a fact that influences housing and
management. Heavy breeds used for meat production cannot do more than flap their
wings and jump to a little higher level or move more rapidly along the ground. he chicken
has pneumatic bones, making its body lighter for flying, although most domestic chickens
have lost the ability to do so. The lighter-bodied birds can fly short distances, and some
can fly over relatively high fences.
The chicken's temperature is about 107 degrees to 107.5 degrees F.
Chickens have comparatively short life spans. Some live to be 10 to 15 years old,
but they are an exception. In commercial egg production, birds are about 18 months old
when they are replaced by new, young stock. It takes close to six months for a female
chicken to mature sexually and start laying eggs. Then, they are kept for 12 to 14 months
of egg production. After that their economic value declines rapidly, so they are disposed
of when they are about 18 months old.
Chickens and Eggs in the Economy
Poultry and eggs are a comparatively cheap food of high nutritional quality.

...ws and beak becoming firm and horny. Embryo fully covered with feathers. Albumen nearly gone and yolk increasingly important as nutrient. Day 17 Beak turns toward air cell, amniotic fluid decreases, and embryo begins preparation for
hatching. Day 18 Growth of embryo nearly complete. Day 19 Yolk sac draws into body cavity through umbilicus. Embryo occupies most of space within egg except air cell. Day 20 Yolk sac completely drawn into body cavity. Embryo becomes chick, breaks amnion, starts breathing air in air cell Allantois ceases to function and starts to dry up. Day 21 Chick hatches!
Hatching day
Two of our chicks hatched right on schedule. One seemed to be "handicaped."
When it hatched we noticed that what we believe to be it's intestines were protruding from
it's anus. It died only a few hours after it hatched. We have just cause to think that this
disformity was due to the fact that some of our classmates were shaking the eggs. The
other chick is healthy and we are continuing to raise it.

Would a person ever have thought that eggs could be scared of something, or that eggs could have their own thoughts? Well , Laurel Wint
Most of the bones are pneumatic, meaning they are hollow and filled with air spaces connected to the respiratory system. Thus the hollow bones reduces the weight of birds which makes the lighter to fly freely.
The piping plover usually nests on the sandy beach, some distance away from the water and is often located near a large rock or clump of grass. There are usually 4 eggs in the nest. The eggs begin to hatch for 25 to 30 days.
Chickens are one of the top most tortured animals in factory farms. Farmers get the most money for chickens that are heavier and have enlarged thighs and breasts. Like most factory farmed animals, broiler chickens are raised in overcrowded cages their entire life, and become very aggressive. Because of this aggressiveness the employees of the farms cut of their beaks and toes without any type of painkiller or an anesthetic just to keep them from fighting. After being “debeaked” some chickens are then not able to eat and starve. Layer chickens lay 90-95% of the eggs sold in the U.S. (2013b) The torture starts the day they are born. Chicks are placed on a belt, where an employee than picks up each chick to see if it is a male or female. Newborn male chicks are thrown into trash bags, ground up alive, crushed, and killed many other inhumane ways.
Broiler chickens, luckily for them, only live up to 7 weeks old until they are big enough to be slaughtered. Their life starts out in incubator trays with hundreds and thousands of other chicks without enough head room to stand up, and not enough room to take 2 tiny steps. So for the first week of their lives it goes from cramp trays, to cramp boxes, to getting dumped onto the filthy floors of t...
The chicken is no longer simply viewed as food and is instead seen as someone or something that cares about the family due to her new role as a mother. This is depicted through the words of the daughter as she states, “Mama, Mama, don’t kill the chicken anymore, she laid an egg! She cares about us!” (129). Thus, it can be interpreted
chickens will suffer for minutes until they finally meet death. All because the farmers cannot be
represent in real life. Birds are a part of a class of animals that have the ability to roam
While there are many reasons a person may wish to raise their own chickens, not everyone in their neighborhood may support the idea. Chickens frequently make noises, which may disturb those with sensitive hearing. Also, negligent practices can lead to odor problems. This is especially a concern to those in areas of warmer climates, such as the Central Valley where temperatures often reach over 100 degrees Fahrenheit in the summer. Ordinances are already in effect in most cities for dogs and other pets. Whether they require owners to obtain licenses or serve to restrict the general noise level in an area, these laws are usually in place for the protection of both the animals and the humans that live among them. It seems only fair that if chickens are considered acceptable pets in an area, current laws should be amended to include them or new, similar protections should be put in place.
Poultry production is a very important and diverse component of Northern American agriculture. Poultry products including eggs, chicken and turkey meat have been an essential part of the diets of most Americans throughout history and other individuals all arou...
One reason most have them is for the eggs, chickens produce about 1 egg a day depending on the breed. When you raise your own chickens you control what they eat and they give you wonderful eggs in return. Most people think it is the same as a egg we buy at the market, well it isn’t. If you have ever had a farm fresh egg you will not want to buy store eggs again. The eggs that you buy at the market are from farms, but mass production farmers. These poor chickens are bred just to provide eggs; they usually are in a box/cage or a room with many, many other chickens. Feed only a mix that is usually the cheapest, no bugs, no grass. I mean the eggs are “normal”. They get shipped to a warehouse where they sit and wait to be shipped to markets all over. They have a expiration date because FDA requires it. Fresh eggs can sit on the counter without refrigeration for weeks, as long as they are not fertilized. A chicken that has access to a run with bugs, worms, grass, treats they get a little extra, so they produce an egg that has a deep yellow/orange yolk. It is so much tastier than a store bought egg. Chickens can also be considered a pet, me I picture myself with a cup of tea sitting outside near my garden with the hens roaming around. Like I would my dogs or cats, they will come up to you; kids can even pick them up
When the colony becomes well established, the queen begins to lay some eggs that develop into queens and males. It takes a few years before a colony becomes large enough to send out winged males and young queens to start new colonies. The cycle will now begin all over again. Nests come in all shapes and sizes. One tropical species built a nest that extended forty feet below the surface of the ground.
Gamecocks are given the very best of care. On the other hand, meat chickens are given the very minimum in care. Meat chickens are going to be killed at six weeks of age, so there is no reason to pamper them. Gamecocks are admired for their courage and are given expensive feed and grain mixtures and are provided fresh water and sunshine at all times.
Neck and beak – *The neck is long and felixble as a result bird is able to rotate its head for reaching food and can see all around. *The jaws are teethless and are produced into beak which are variously modified to pick up food, making nests and preening etc. Skin – *The skin of bird is loose which allows movement of the flight muscles. Limbs –*Forelimbs are modified into wings and are attached closer to center of gravity and farther from head than in other animals. *The wings act as propelling organs for flight. *Hand bones are small, fused, flattened and specialized to manipulate the flight
