I have 3, 2 1/2 yr old hens. I recently got 3 more hens, that are about 3-4 months. They have been in coops side by side for 2 months. They have free ranged with minimal issues. I moved the little hens in after expanding the run size. However the little girls are being picked on. Not horrible, but they won’t fight back and now their not leaving the inside coop. It’s been 2 days. Any suggestions? No one is bleeding it’s more threatening and pulling a few feathers.
