I read somewhere that some silkie breeders were keeping their chicks in a brooder with a wire bottom until they were 1 month old and then switching them over to wood chips. Is anyone doing that? Is it because of foot issues or something else? Curious because I have had a couple of chicks lately with splay leg and I was wondering if keeping them on wire with the padded shelf paper on top to start would be better than wood chips underneath them.
