When should I put mama hen back with the other hens and keep chicks separate? The chicks are hen hatched and raised living with mom in a separate section f the cop and pen. At 5 weeks they are hoping all around her and on her. Does Ebony [MOM] need a break? I have 2 hens with their chicks in the "nursery" section. One mom [Buffy] is kinda aggressive to Ebony. I am new to this and would appreciate any advise. Thanks. Elena 5 hens, 13 chicks, 1 cat, 2 dogs, 1 rabbit, 4 Dwarf Nigerian goats and my kind husband.
