My once fluffy, healthy-looking girl, Speedy looks dirty, haggard and thin all of a suddon. Over the past few days, the feathers around her head and neck have disappear and she just looks dirty and sad. Still has a lot of energy but I am worried about her. Anyone know what might be up? None of my other chickens are molting so seems unlikely that would be the case. Could she be sick or getting pickle on?
