I have a 9 year old silkie roo. Him and his now deceased 2 mates are the only silkies I've had until this point and even with roosts available they never roosted. They never went up and slept on the ground. The roo still doesn't. He'll sleep under other roosting chickens. I have 3 silkie chicks and I was wondering if this was normal for silkies? Will my chicks also never roost?
