My runaway broody has succeeded today in hatching baby chicks in a crack under our house. I haven't seen them yet but heard them. The little problem is that it's night here now and I can still hear them chirping clearly. They seem to be with their mother, I can hear her clucking in the same spot. But all this noise at night can't be good. It's bound to attract every predator in the area. Why do they do that?? I've got 2 other hens with chicks right now and they keep quiet at night. What can I do to make these suicidal little crazies shut up? I can't just pull the hen out of her hiding place because it's too narrow for a human to get in.
