I have a very simple chicken pen at the moment - 2 connected 10x10 dog pens. It has a roof and floor of field panels wired to the pens because we have tons of raccoons and hawks. I got my chicks in April as tiny babies and the hutch I got when I bought them was plenty big enough. They aren't tiny any more! They need a coop. Right now, the only thing they have for shelter is a tarp over 1/2 the original pen, the hutch and the trough (on it's side) that I kept them in as chicks. They were so cute as babies. If they got scared, they ran for the trough. They roost on either on an exposed 2x2 (under the tarp) that goes length wise across one pen or on some limbs that I have in the corner of the first pen. All of their "coverage" is in the original pen. That's where they sleep and lay. They caught me off guard when they started laying at four months! I didn't have anything ready. They use the hutch as their laying box. They need a coop for winter. The easiest thing for their coop would be to put it in the second pen - what I consider their run. How easy is it to teach chickens to roost somewhere else? I don't know if I could convince them to roost inside in the second pen. If not that, I could rearrange the first pen and put the coop under the 2x2 that most of them roost on and move the hutch to the other side of that pen. How well do chickens deal with change??? Opinions???
