My silkies free range, but they stay pretty close to the chicken barn door. I do have some that find their way to the lower and middle perches at night. A few find thier way to the silkie pile in one corner of the mesh cage and a few are always about the barn in one corner or another. I have to gather these up and they are usually the same birds. I have never really had a problem with them in the flock. I do have one roo silkie that will take on bigger and meaner roos than hisself. So far no fatalities.
