One of our two polish chicks is having her top knot pecked at and has a bald spot now. We looked at TSC when we stopped by there today to pick up some other needs and they didn't have anything to help. I have found some things online that would work made specially for chickens but in most cases, the shipping is just as expensive as the product itself. I have heard that pet stores do carry sprays to keep pet birds (canaries, etc) from picking at their feathers. Would that type of product work on chickens too??
