I now have a new coop for some Silkies and need some advice on the inside finish. How high should the roost be and will they use nest boxes at the same height as the roost? I don't know if I should apply the same ideas I have used in my heavy breed coop which turned out very well. Some say their silkies all sleep on the floor. Do they also prefer nests on the floor? Thanks all coop builders for your suggestions.
