I haven't had that fault pop up in my birds. I wouldn't use the bird for breeding and both parents would be removed from breeding since it's recessive so both carried it. I do this with most disqualifications. If it's from crossing in another breed for a trait, that takes much time to remove it...
The evil things will go stand on their treadle feeder step when the birds manage to get in. Then they wait until the little bird takes the bait and flies down to grab food. Silkie then jumps off the treadle.
I had weights on the lids that silkies can just open because of too intelligent rats...
Responded to a question in the byc facebook group about ugly coops. I don't think mine is very pretty.
This is my set up. All 5 pens open to a courtyard for safe "free ranging". It's on the west side so the walls stay tarped year round as I found it keeps it cooler inside.
Back of pens...
