This chick is about 10 weeks old. Raised by Mama & not as friendly as my brooder chicks usually are so he is kind of hard to get close to. For a couple weeks I've noticed that his comb looked black but I figured it was just how he is. Today I got close enough to grab him & see. His whole comb and all of his head are covered with black, puffy things that look like warts. Has anyone seen this? Any clues? I didn't have my phone so no pictures. What do you guys think?
