Question about missing black pigmentation on one wing:
I have a silver-laced wyandotte hen who, after her molt, came in with all white flight feathers on one wing. No black edging at all on about 6 to 8 of those feathers--just the long flight feathers, not the whole wing.
At the same time my barred rock rooster developed an all-white feather in his tail. Just one feather at the top. Any thoughts?
Background info: They're fed a poultry mash from my local mill plus they get either wheat sprouts or fermented scratch every other day (I alternate the treats and they get only enough that 8 chickens can clean it all up in 10 minutes or so). When there's snow on the ground they have access to an enclosed run that doubles as my compost pile. I put in a lot of fresh horse manure this fall.
Other info: I have two bantam Australorp hens and one went through a molt and all her feathers came in perfectly black, like normal. No missing pigmentation for her.
Any tips would be appreciated!
