I had to separate broody from flock while she was sitting on eggs because everyone uses only 1 box like the other one is cursed or something. They'd continue to add eggs and she'd take them. Makes staggered development, ones she'd end up leaving for whatever hatches within 3 days of first chick. When her chicks were not quite 3 weeks old I put all of them and mom back in her breed's coop at feed time. Momma did a smackdown on 2 others trying to check out the chicks then all was right in their world! Momma went to dustbathing with chicks surrounding her so I knew she was comfortable. I should mention that the roo had already been separated weeks earlier. Now everyone gets along great like the chicks were there the whole time. I vote with the others- mom will protect them. And less worry for you since you don't have to make sure the brooder stays just right
No pasty butt and healthier chicks too.
