I have six silkies and 2 rhode island red hens that have grown up together since day one. They are now a little over 5 months old and the rhode island reds still sleep on the ground with the silkies. I know that they can jump on their roost. It is plenty of room for the two of them. I swear that they think they are silkies! Any ideas on why they don't roost at night and how I can get them to? Any help is very much appreciated!
