Hello!! We used a shower curtain rod in our brooder for them to roost on. I sure you could use any material for the roost. Our rod seemed a little slippery at first for them so we wrapped duct tape around it for traction. Obviously, sticky side down! Good luck!
I'm just using a tree branch in my brooder right now. I've also seen people use 2x4's in their henhouses with the 2" side up for them to roost on. I would assume that anything that isn't slippery or that they can get a good grip on would be okay. Of course not the poisonous plants, but anything else should be a go! Happy Chicken Raising!
Wood gets my vote. Chickens don't perch like other birds; they literally sit with their feet as flat as possible so they can balance the weight of their breasts. Some mods advise using a 2x4 with the 4" side up! That would work for young chicks and also very large chickens.
That's not exactly true airmom, chickens can perch like other birds with no problem. I do agree with the wider roosts if you live in a cold climate if you want to keep the toes on your fowl. In most cases though, the 2 inch side up will be wide enough for the birds to cover their toes, but some breeds that are tight feathered need the 4 inch side up to be safe. BTW, I use wood because it doesn't get cold like some other materials do in the winter, so it works better for them to avoid frostbite this way too. Good luck!
