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! 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.
