I acquired a pair of silkies that I have incorporated into my flock of hens. It took a week or so but they all seem to be getting along fine. My question is that one appears to be a rooster and has started to try to crow - do silkies eventually crow as loud as full sized roosters? and someone told me that they do not "fly" so can they roost? I have conventional height roost bars and nesting boxes do I need to make accommodations to my coop for the silkies? THank you for your help!
