So, I have 17 hens and two rosters. There is three different breeds both of my rosters are of a different beed. My question is that my roosters will sleep in the run at night and one hen will be with them. During the day they are all let out to free range. I also have a hen that roost in a tree next to the coop, I usually just put her in the coop after dark. Is OK to let them roost in the run even though the temperature is starting to drop to the mid to high forty's even though it will start to get colder?
