    We HAD a rooster and hens. Then two months ago we got rid of our rooster in the process of getting ready to move. Now we've moved, and have been without a rooster for over 2 months. I had not been feeding our hens layer feed because of the whole move and getting settled in thing. I started back with the layer feed a week ago. I started getting eggs from our girls immediately! YAY! This morning while making sunday breakfast I noticed our eggs are still fertile?

    Why? Better yet how? I had to show hubby just to make sure I was seeing this right, a bullseye in the yolk! [​IMG]

    I thought two weeks tops till the fertile eggs stopped? We were without a rooster for close to a month before moving and were getting eggs the whole time, but I never thought to actually look at any for the bullseye.

    From what I've read here from other posters, hens have an organ that allows them to store semen - probably a holdover from their wild genetics when a hen never knew how long shed have access to a roo to lay a clutch of eggs to hatch. The semen can be stored there in a viable state for several months!!

    Someone with more chicken knowledge may come along and correct me, though, so don't take this as gospel! Good luck!

    Even on non fertile eggs the nucleus is readily visible. This may be what you are seeing. Two months is way beyond the 'sperm storage' capability of a hen's reproductive system.
