My 5wk.old chick has developed these lumps that have crusted scab on top of them.At first they appeared to be areas she had picked at when her feathers were coming in now she has more of them first just 2 now I counted like 5 of them on various areas.I looked up blow fly lesions and they don't look like that.She is on straw could she be getting something from that?I looked her over no mites or lice maybe a vitamin defiency?She is on medicated chick starter 20%protein.
