I have a five year old Silver Laced Wyandotte who has been looking strange for a few weeks now and today I finally realized what it is. Her face is a very sickly looking yellow. I hadn't noticed the color until I pulled up some old photos of her this morning, just mostly from her standing around sort of 'compact' like she was cold. I feed organic layer, she has two hen-mates that are different breeds who look and act fine. Please help, I'd hate to have anything happen to her, they are older now and don't lay as much, but I've gotten attached to them!
