Recently for the past few days or so I've noticed two of my chickens have this weird sore-type thing on their waddle and comb. The white leghorn seems to have it the worst but it looks like it is slowly creeping up on my blue andalusian as well. They seem to be walking around foraging as usual. They are cage free, and we live in a country-like suburb. What is it and how do I get rid of it? Sorry they are sideways I had the hardest time trying to rotate them, then save them appropriately to upload onto here so i just gave up.
