I just got 2 hens yesterday the owner said they were Hatch & Punpkin Hulse? Or however you spell it. At first they were separated and when we got them we put them into the same pen. It's pretty big. When we first put them in one hen takes advantage of the other and starts pecking at her and she flees into the coop. And at night the bully nest outside and the other one nest in the coop? Should I seperate them?
