I have a bantam roo who's comb,wattle and face contantly changes. I mean, 1 day he's red parts are bright red and then a pale red the next. then he,s red parts turn normal for a few days then he getssmall,small spots on his comb then they disappear. Then he's redness randomly changes. Is there something wrong with him because he's behavior is normal and he eats and drinks normally. Could it be early signs of fowl pox?
