About 2 weeks ago I noticed one of my RIR having some feather issues around her neck and belly at the time I assumed it was a weird spring molt. After a week her belly became completely bare and started turning red. I had already looked for mites and found nothing but still treated her for mites/lice. After that treatment I started spraying her belly daily with Vetericyn. After a week no improvement. I decided yesterday to isolate her in the house along with that she got a bath to clean her up good. She is eating, drinking and pooping fine. Not sure about egg laying yet as she has not laid since I moved her indoors. After her bath I wiped her stomach with some witch hazel and plan on putting some GreenGoo Animal First Aid ointment this evening. Has anyone got any ideas what could be causing this and any other treatment plan that might be better than what I am doing. Pictures attached. The first 2 pictures are from after her bath the second 2 later that evening after I cleaned her again with witch hazel. Thanks in advance for all of your help
