We only have 2 chickens and one was taken by a predator. Today we got 2 new hens, who are about the same age as our remaining hen, about 17 weeks. We only have one coop with a fenced in (and safer!) run area. I am a little nervous about when they go into the coop tonight, since that is the only place they can coop at night and our first chicken has already been picking on the new ones. I am afraid that she will really lay into them tonight when they are locked inside! Any suggestions??
