New to the board so hi all,
I have 6 chickens. 2 RiR two buckeyes and 2 EE's. about a month ago I noticed the reds had a white powdery look to their combs. After doing some research I thought it might be favus. I treated them for a month and it seemed that it all went away. The treatment caused the RIR's combs to get real dirty so using a tooth brush I cleaned them both real well. Well today after about 4 days since I stopped treatment I noticed that their combs are back to having a white powdery look to them and I am wonder what the difference between dry comb and favus is? Could the treatment caused their combs to dry out? I will try to post pictures when I can.
