Hi all, So a couple of days ago I noticed that one of my white leghorns has a very droopy comb. The rest of the flock (including two more white leghorns and 5 more mixed) are all fine. She is acting fine otherwise, eating, etc. But her comb has basically crumpled waaaaay over-- not like it was before at all. It seems even worse today than it was a couple days ago. It is the same color as usual- a dark red. I don't think it's frostbite, as it hasn't even gotten below zero here yet, and the others are all fine. Any ideas?
