I have 2 RIR girls. We got them around May of this year from someone who couldn't keep them. One has always looked pretty good and the other usually looked ragged (Scarlett). They had lice to I treated them with DE. They had worms so I bought wazine and treated them. Scarlett looks bad. The majority of her feathers are all broken or missing; there are none on her butt. But her spirit has always been high. Today she seemed different. She just stood in one place with her feathers all puffed up for a long time. I decided to let them run around the yard, but she didn't care that much. They're housed in a 12x12 pen that has nesting boxes, a perch, and plenty of room to scratch and dig. They get as much Layena as they can eat and treats every day. Today they got yogurt. It did get pretty cold here last night (for GA) and the night before, but I'm not sure if that could have anything to do with the problem. Surprisingly, both girls are laying pretty well right now. Scarlett has laid 3 eggs in the past 3 days. Any ideas? Any help would be appreciated!
