Yesterday I belatedly noticed a full tick latched on at the bantam's ear. It literally fell off when I went to remove it (then fell to the ground where one of the other chickens promptly ate it - bleeeech!). This afternoon, I noticed that the wattles on the banty that had had the tick on her yesterday are uniformly grey/ blackish - almost the entire wattle is discolored. The hen is fine in all other respects - laying, eating, drinking, ranging, etc. Any thoughts on the discoloration of her wattles?
