Reproductive System of Chickens

tube that connects the chicken's testes with the cloaca and stores sperm. Roosters don't have a penis. Instead, the tubes end in the papilla, a little bulge in the cloaca.

Vas Deferens

is a cluster of tissue sacs containing tiny egg yolks, or ova.

Ovary

funnel-shaped muscular part of the oviduct that pulls the ovulating yolk from the ovary to start its journey in the oviduct.

Infundibulum

the part of the oviduct where the egg white forms around the yolk

magnum

the part of the oviduct where the inner and outer shell membranes form.

Isthmus

In a chicken's __________ or shell gland, thin albumen builds around the yolk and the eggshell forms.

Uterus

Shell Gland

Where the eggs, droppings, and uric acid all pass through

Vent

When chickens mate, the rooster gets on the back of the hen, and they press their cloacas against each other.

Cloacal Kiss
