Yeah, I have branches stuck through chain link for run roosts, but they're not intended for night time use. Otherwise yes you're risking raccoons especially being able to reach in and tear out pieces of chicken.I recommend not allowing the wood to go all the way to the chainlink unless you wall off where the roost meets the chainlink. Chickens will sometimes roost right against the chainlink and Ive had coons pull chickens through the wire or just pull their heads off through it. So if it does butt against it make sure you have something covering up that area like a piece of roof tin![]()
