How does the sperm get into the chicken egg?

Answer 1

You don't get "sperm" in an egg. You get a germinal disc and unless you know what to look for, you would never see it. The germinal disc sits on top of the yolk and is almost microscopic. Fertilized eggs are pretty well indistinguishable from non fertilized store bought egg.

Bet you thought the white stringy thing beside the egg yolk was sperm, it's not, its called chalazae and is a protein strand used to hold the yolk centered in the albumen.

Answer 2

Not that you could see. If you are referring to the white stringy stuff at each side of the yolk, that is Chalsae the protein that holds the yolk to the albumen.

When a rooster fertilizes the hen the sperm does not all go to one egg, it can fertilize eggs in the same hen for 10 days. Only a small amount of sperm gets to each egg and it goes into a small spot on top of the yolk that you cannot see.

Answer 3

The rooster chooses a hen and approaches her. He will do a little side step dance by spreading his wings slightly and lowering his wings to touch the ground not unlike the position the hen must take for his mount.

He will do this dance moving closer and closer until he can grasp her by the neck feathers with his beak. He may also lightly peck her head to get her to take a mating position. At this point the hen should take a submissive position as close to the ground as possible allowing the rooster who is still holding her feathers to mount her back. He will place both feet on the hens "saddle" the area on her back that is just above the tail. Most hens in their prime will have bare patches in this area because of the roosters attentions.

The rooster, once he has gained his balance on the hens back will lower his vent or cloaca and his tail will lift slightly, the hen will lift her back end and cloaca at the same time and the cloaca will invert, then both will touch. A sperm sac will leave the rooster and enter the hens vent, sending the sperm sac on its journey up into the oviduct. Hen and rooster will not actually need to mate again for several days since there are enough sperm in each sperm packet to last for about 5 to 8 eggs. The rooster will dismount and the hen will shake, dust herself off and smooth her ruffled feathers, she will then go about her daily hunt for food, meanwhile the rooster will immediately search for another hen and start the process all over.
