I am building coops for my new birds, and I have 4 black silkies. So far my coops are elevated, with the entrance inside a closed run for extra protection. So far this has worked for LF well, only one loss to predators while foraging this year. I have read that silkies don't like ramps and won't use them. I was thinking the coop with the silkies would have a 12" wide ramp and I would use the safety strips used on stairs to provide traction. I could also put guard rails about 4" along the side. I hope that would make them feel safe using the ramp. Inside the coop I Will have a Banty room immediately to the right of the pop door that will have arched entries about 8" high. The room would be the same size as the next box unit, 45" x15"" with the exterior wall that flips down to allow cleaning and egg and broody care. I was thinking I could house them with either the EE's or NNs since both are fairly calm. The NN are down right mellow, even as adolescents they will let me hold and pet them.
