My roo is not well and I am keeping him inside tonight. Is it okay to cover the dog kennel he is in with a bed sheet to keep him from crowing too early in the morning? I am trying to keep a delicate balance of dogs, sleeping child and rooster in on small house. I have had hens in and never would have covers them. I covered three sides and the top and left uncovered side facing wall, away from windows...no window-less options available.
