I say "think" because this is all pretty new to me. I have one hen that has separated herself from the group mostly. We mostly free range and she has hidden her nest, and is not going to roost with the others in the coop at night. Is she brooding maybe? I'm in TX, is it too early in the winter for her to have little chicks to care for? Shes a Buff O if that makes a difference. I cannot find her for the life of me, but in the morning she is always on the porch and walks out with me to let out her buddies. Next question, we lost a roo last week...a neighboring doggie got it. We got a new Roo, and after one day he has vanished...no sign of him. Should we have left him in the coop for a while first? We put him in last night, let them out this am, and came home from church to find him missing. I didn't find any feathers, I don't think he was taken by a predator...any thoughts on why he would just vanish? I'm really hoping he is holding up with my hen that is in hiding. Update* he came back! I'm so pleased. So now what? Do I lock him up, or wait for the night time routine, and then put him up with the others? Do I still separate him?
