Thanks Ridgerunner, they don't free range, they are in a coop with a rambling run which covers quite a bit of the garden, there's no stray eggs in it and no predators, only sheep in the fields next door. I'm curious about the moult (UK spelling) though. This was their first one, and they didn't start until late December, I read it normally occurs in the autumn. The Calder ranger had the most obvious one, her comb is still smaller and pinker, the other 2 just lost a few feathers and looked a bit scruffy, their combs etc are nice bright red.
