I added 4 new chickens to my flock this summer. They were put out in the runs and large coop(where they roosted every night) separated from the rest but able to see for about 6 weeks and then integrated. Things have been fine all summer. We have a chicken porch in the enclosed runs and the 4 have taken to roosting on the poach rail all summer. Now the weather has turned rainy and cooler 40-50ish) and it is not covered. It poured rain and hailed the other night and they were drenched! I hoped they would moved back inside but have not. Help
