Can I just add more roosting space to my existing (pre-fab) coop, or is it possible to add another small coop to the other end of our run? My husband is building us a beautiful run for our girls, but we had purchased a nice pre-fab coop (says 4-6 chickens). We have four girls, but are thinking of adding two more. I don't think our current coop would have enough roosting space, though it does have enough nesting boxes. If I had known my husband had secret carpentry skills, I would have had him build me a coop too! I am likely going to a nice farm today to pick up some new young pullets for myself and a friend, but I am worried our current coop will be too small when the cold months come and they're all inside more often. Any advice (other than to say don't get more pullets...I've always wanted an Ameraucana & a lavendar Orpington!)? TIA! PS - We have the room on a large corner lot on the edge of town for free-ranging, I'm just worried about hawks.
