I am a new chicken lady. I had four chicks that turned out to be one hen and three roosters. Gave the three roosters away and today introduced a new hen to the hen I already had. The new hen (Buffy) is definitely the dominate hen. Agnes is the hen I already had. Tonight Agnes is sleeping on a roost a foot off the floor (outside in the run) and Buffy is roosting on a high roost about a foot from the ceiling (inside the henhouse). I am worried that Agnes is out in the cold. How long before they can live in peace together?
