My hen hatched 3 chicks Thursday and Friday. They are in with the other hens in a raised coop about 3 feet off the ground. Mom and babies are in a nest box on the floor of the coop. I'm worried about them falling out of the coop. When would it be ok to let them have access to the ramp to go in and out with mom? And about how long before mom wants to take them outside? I don't think she has come out of her box for a couple days. They have their own food and water in the box. Sorry for all the questions, first time letting a hen do the work for me and first time broody.
