Ok, I am such a total newbie, please help! I have 6 adult hens and 8 young chickens we got as hatchlings in May. Two of the hatchlings have turned out to be roosters. The other day my son noticed what we thought to be mating behavior between one of the roosters and one of the other young chickens (pullet?), we giggled and moved on. Monday, we went out to check for eggs and one of our adult hens was camped out in the nest box. Ok, maybe she is just resting. But she hasn't moved that we know of since (3 days). Is it possible she actually has a fertile egg under there? Is it wise to let her sit it this late in the year? I would love a new baby chick, but man I feel so in educated!!
