Hello, this is my first post and I have a flock of around 40 with a separate flock of 6 silkies. Almost all of my hens, with the exceptions of a few RIR's, a few Buff Orps, 2 blacks australorps, and 2 spitchzhaubens experience extreme feather loss in the area where our rosters mount them. I only have 3 roosters in my big flock. This doesn't happen at all with my separated flock of 3 silkie hens and 3 roo's, and yes I know that's a bad ratio... Is it the roosters or something else? I know that removing the roosters would help but I don't really want to do that.
