I picked up 5 hens yesterday as a favor for a friend leaving overseas for a half year. Just a few days prior he noticed they were picking at each others butts, and by the time I picked them up yesterday they were horrible. Here is the info, any help would be appreciated. Breed: RIR I think Eating habits: Great. Eating and drinking well. Food:some sort of grain for the last few weeks before I got them, now on good pellets and treats and bugs. Access to grass. Poop: normal brown, little white. Attitude: docile, easy to handle and very alert. Butt Condition: no fluff or feathers. Bloody scabs. Little bit swollen were there is scabbing but other than that fine. 2 Are badly scabbed, 2 are slightly, and one is minor. I have checked for mites/lice, found nothing, and dusted their new are just to be safe. Please help me help these bald butt girls.
