Chickens are in a big walk in run with a perch they like which is high up in one corner. I am still going out at night and putting them in the coop ( for warmth- I don’t think anything can get into the run) . This involves taking them off the perch where they seem happy and manoeuvring them into the coop. Is there any point or will they be fine left out? I don’t like to think of them getting cold!
