Well, they are free range. In the petting zoo. There is some protection from the elements, and there isn't many rodents there. I will see if I can chicknap some more if she has 7 still come Sunday. How long before hens will wean? I've got a hen with atleast 6, if not 8 week old, maybe even 10 week old chicks.
They usually lose interest in the chicks after they feather out, 4+ weeks. Then they don't need mama to keep warm and can easily roost to stay safe. That's the hardest part about raising the ground birds, avoiding predators until they start roosting.
