I've read on here that a lot of people use 2x4's for roosts in the winter. Well, I've got 11 bantam cochin chicks and I'm getting the coop set up for the winter. Is a 1x3 strong enough to support them? I will have 3 roosts available, so hopefully they all won't get on the same one. Also, each roost is only 4 feet long. I saw these at the lumber yard today...they'd definitely be easier to handle/install, plus much lighter weight.
