My broody hen hatched an egg, so I separated mom and baby to their own pen. Mama was ok at first but now she is a wreck, she paces and is losing a lot of feathers and doesn't seem happy at all, I don't think she is eating well either. The chick is three weeks old and I'm thinking of bringing it in the house and placing it in a brooder. At the same time I want to move mama back to the coop during the night and place her on the roost with her flock mates. Any advice would be appreciated! Thanks! Additionally, I will be getting 13 new chicks next week.. can I keep the current chick with the new ones?
