I was able to grab my two leghorns today, and bring them in the house to treat the combs. I have photographed what it looks like so far to compare if it gets better/ worse in the next few weeks.
The cat food was of interest to Lady, who appears to have some frostbite on one of her wattles. I put neosporin on the combs of both her and Spike, the other leghorn.
Does anyone know if her tail feathers looking ragged are a bad sign?
The tail feathers have no correlation to the frost bite.
Also, I think her points look pretty good, I wouldn't worry about them.
