For the past few days I noticed my chickens have been losing feathers a lot and the other day they had a whole lot more missing. It's 2 chickens that are loosing feathers. We put on chicken lotion that is suposed to discourage them from plucking themselves incase they were pulling their own feathers. Anyways because of the lotion they have the bald spots dyed purple. I'm just wondering if anyone has thoughts of what it is/ what is happening. The picture is of the one with the most missing feathers.
