Hi! I've just noticed that my 2 year old Buff Orpington has been acting odd. She doesn't come when I toss scratch on the ground anymore. She sits in the shade while the other chickens forage. Her comb and wattles are also seeming darker than they used to be. About 6 months ago some new chicken brought lice to the flock, she and a few others got them. I did bathe her, and the others that had lice, but they seem to have come back. Would the lice have to do with her problems? I know that they can cause anemia, but her comb is darker not lighter. Any help is greatly appreciated!
