Thanks for the info. I researched depluming mites, and I don't think this is my issue; however I have not ruled it out. My peepers just came, & unfortunately due to long work hours this week, we have not gotten to put them on Bertha yet. I really hope they sole the problem as I feel terrible about keeping her by herself. She was free ranging for one day with Percy, and it did not take long until I caught her pecking Percy's butt & causing her to bleed again. Other than that, they play so well together; always side by side. I hope to have the peepers on by this weekend, and I will let you all know how it goes.
