I have 5 Key West hens and 2 roosters. I only keep 1 rooster in with the hens. The other is in his own pen. I would like to start selling eggs but want to use the other rooster also, since he is younger and prettier. If I take out roo #1 and put in roo #2 for a week, will the resulting offspring be both roosters? How long will it be before roo 2s sperm are also in the works? I dont need for them to be all his, just would like for some of them to be in there.
