Once momma comes out of her trance, she should run defense for the chicks. The other hens will peck if the chicks invade their space, but not violently attack. The chicks will quickly learn safety is under momma.Ok. I can do that. The boxes are bigger but not so big as to have room even for a chick sized feeder and waterer. I might just pull the wire off one of my windows and move it down. I can close one window for a day. I’ve got plenty of other ventilation. Thanks again. Hopefully after a day the other d’Uccle will calm down and not bother the chicks.
