Egg Science Fair Project

My family and I have been raising two chickens for the past year named Hen and Red. They are both hens of the Red Comet variety and they lay large brown eggs. We do not have any roosters, because we simply like to keep a solid supply of fresh egg is in our refrigerator and do not currently want any chicks. They both produce eggs, which my family enjoys in everything from scrambled eggs to mixing them into cake batter and making homemade waffles. The whole process is very interesting and that is why I chose to do my Science Fair project on egg production. I would like to see if different brands of feed produce better egg results in terms of size. I found that the most fascinating part is the actual process in which a chicken lays an egg.

The egg process begins with a tiny gland in the eye. The gland is light receptive and when it registers light it releases the egg cell from the chicken’s ovaries. The egg then travels down the uterus, where it eventually grows into a yolk. The uterus fills with a jelly substance called the albumin, which is the egg white. A membrane then develops around the perimeter of the walls of the uterus sealing the whole yolk with the …show more content…
This forces the egg to move down the vaginal canal to an opening called the vent. This vent is connected to the intestinal canal, which is also were it releases waste. Half way through this process the egg will reach an internal flap. The flap will only allow one egg to release at a time. Once the egg reaches it’s highest point, the intestinal canal closes back up so nothing else could come out. The chicken will stand up and lower it’s back which will cause the vent to become as wide as possible. The contractions turn the chicken’s canal and internal flap inside out causing the egg to drop out of the canal. This completes the process of laying an egg. (Explore Knowledge that Amazes
