My broody is still sleeping with the chicks at night, but I'm noticing during the day she frequently is chasing the chicks. (especially the boys) The chicks are now 7 1/2 weeks old. I don't want to stress her out by taking her from her babies, but I'm getting the feeling she might be wanting to go back to being a normal hen? Should I put her back in with the adults and let the babies be by themselves?
