I have 3 Australorps. I noticed two of them had some white spots on their comb yesterday. Today it looks more inflamed. They are about 7 months old, all are laying. They free range in the day but sleep in a coop at night. Coop has pine shavings and I dust with DE when I change the bedding. The seem to be eating fine, none look sick. poop is good but every now and then some have a little runnyness to them.
Anyone know what this is and how I can cure it?
