One of my Wyandotes has a crusty eye and a swollen wattle. She acts healthy and normal. I do not notice any smell and do not see anything coming from her nose at all. She is a gorgeous plump bird and I would hate to cull her. Is that what I should do? Wouldn't all the other birds get it as well since they share a coop? Ugh!! I am thinking I will lose my whole flock. No other birds are showing any signs. Where would she have gotten this?
