I have 4 hens and 2 roosters. We got 12 baby chicks and this is what we have left. We have a lot of trouble with hawks so my husband built a little completely closed in pin for them and put a little house on the back, any way those chicks are not about 7 months old and very good layers I have one hen that actually went to the little house, away from the rest of the hens and made a nest and started laying eggs, we thought she might want to sit on them. She is still spending most of her time in the yard with the rest of the flock, but now my other hens have found her nest and they are all laying eggs there. How long can I leave these eggs before she actually starts to sit on them. And if she isn't broody how long can I still use these eggs to eat. It has still been in the 50's at night and only in the 60 during the day, however it is going to get into the upper 70's this weekend. Any reply's would help. I had an old hen that sat for 8 weeks she only gave up when we put some babies under her.
