I just set up my brand new coop. I had planned on placing two roosting bars made of 2"x4" lumber, placed specifically with the 4" flat part so the chickens would have a wide 4" surface to stand on. (We live in the North and this was recommended so they can completely cover their toes in cold weather.) HOWEVER I somehow lost my brain and nail-gunned them in with the short side up, so the surface to stand on is 2' and the perch is 4" deep. Is that OK or do I need to put the time into changing it back. I don't have any chickens yet (just teeny chicks) so I'd like to do the changes now before anybody moves in and messes the place up. What do you think? Are they OK the way they are?
