Hi there! Not sure how to go about diagnosing what some of my girls have but here is a picture of the dark black spots on some of their combs... I have googled and have read it could be fowl pox... or it could be mite damage. It doesn't seem to be painful when I touch it...I'm not sure what it is being that this is our first ever backyard flock, but I want to get it taken care of right away!! Any insight on what it is would be much appreciated!
