Parts 3, 4 and 5 are missing. Disappointing that you did not use your class time and homework allocations better. Grade = D

OVARY - containing immature and mature follicles. The mature follicles consist of the egg "yolk" and the unfertilized ovum.

INFUNDIBULUM - yolk with attached ovum is snatched up by the infundibulum. It is at this point in the reproductive tract that the ovum is fertilized if the hen has been mated with a cockerel. Spermatozoa from the cockerel are stored in "sperm nests" located within the infundibulum and are capable of fertilizing ova for up to 30 days after mating.

MAGNUM - while traveling through this part of the oviduct, the albumin or egg white is formed.

ISTHMUS - the tough outer membrane located just beneath the egg shell is formed in this part of the oviduct.

UTERUS - also referred to as the "shell gland", this is where the egg shell is formed. Most of the transit time from ovulation until the egg is laid is spent in the uterus.

VAGINA - the egg travels through the vagina into the cloaca, from which it is "laid."

CLOACA - this is the common external opening from which the contents of the urinary tract (urates), the intestinal tract (feces) and the reproductive tract (eggs) exit the hen.
When a rooster mates with a hen, the semen is stored in the oviduct. before the egg is ready to create the shell, the sperm surrounds the egg.
It takes 12 days for a chicken to lay an egg.
An incubator is an artificial machine used to incubate the eggs.
