I could have used one of those neck sweaters a couple months ago! I had a molting hen molt completely bald from the shoulders up and she was picked on so badly I had to put pinless peepers on everybody till she grew in enough feathers to cover her bare neck. At one point they had took a pretty big bite out of her. I separated her for while, but thought she shouldn't have to be caged while waiting for feathers to grow back in, so everybody sported blinders till it was all over.
I am pretty good at crocheting, so I think I will whip one of these up for next year molting season. :-)
