When do chicks leave their mother hen? Ours are about 4 weeks old(to be exact: Peanut-30 days old, Juno-29 days old, and Suzy-28 days old) They are all still following their mother hen around during the day(sometimes wondering a short distance away to explore a little) and she still protects them(last week she attacked my brothers toy plane that landed nearby her and the chicks! LOL) When should they start to become independent? Will it affect them if some stay in the same coop with her when they are older? Thanks!
