One of my 3 year old RIRs has been off and on sickly for months. She nearly died a couple times this past Spring and Summer from losing so much weight. I never did find the cause. Finally, she gained enough weight and energy to go back outside with her sisters. She's been outside, happy, but not laying eggs for about 6 months. Recently, I'd say about the past 2-3 weeks, she's been plump and healthy with beautiful feathers, but beginning to slow down a bit, acting a little tired but not lethargic. I also was thinking that her comb seemed quite a bit smaller. Tonight, when she came out with her sisters to get the scratch before bed, I couldn't help but notice that her comb, wattles, skin around her eyes, her whole head, seemed so dark red that it is almost purple. Any ideas what this could be? I've had, and still have, a RIR inside for a little over a week with (apparent) peritonitis and mites. I don't know if this is at all related, but I thought I'd offer that info just in case. Thanks so much for your suggestions and help. This community is such a help.
