I recently lost all 5 of my chickens in 1 night due to predator. So I purchased 10 hens from someone. I got them about 8 o'clock at night and put them directly in the coop. Some even on the roost. Since then the hens won't even go into the coop or lay any eggs. They eat and drink OK in the run area but at night just gather into the corner of the run under the coop and stay there all night. I've had them 6 days with no change. Cleaned the coop entirely with fresh pine shavings inside and in nest boxes. Any ideas anyone?
