My 1yr old hen recently went clucky sitting in the nest all day, I assumed her faded comb was just due to this. Then it began to get dark spots almost looking like warts of some kind and completely covering her comb. I am also now noticing some spots starting on the other hens who aside from this seem well. My clucky hen is by far the worst however still comes out to eat and drink, but she looks dreadful! Really want my hens back to full health asap, so your assistance is much appreciated! I have attached a photo for reference.
