Bird Reproduction

Birds do not have traditional sex organs in comparison with mammals. They both have a cloaca. This is an opening beneath the tail feathers. It houses the genitals and eliminates waste. The sperm from the rooster is dropped from his cloaca to the female cloaca, where it can remain viable for up to 30 days. Fowl sperm cells have a long pointed head and tail structure.

Hens are originally born with two ovaries but the right is the only one to reach maturity. This ovary produces the familiar yolk of an egg. It takes 10 days for a yolk to develop in the ovary. From the ovary it is released to the oviduct where it obtains the egg white, membrane, and shell. T Egg production is split into five sections.

Infundibulum – yolk fertilization takes place here.

Ampulla / Magnum – creates forty percent of the egg white.

Isthmus – creates more egg white and shell membrane.

Uterus / Shell Gland – produces forty percent of the egg white and the egg shell.

Vagina – secretes shells outer pigment and cuticle layer of shell.
