Update! Her comb started filling in again and she started laying every other day or so, but yesterday I noticed there was swollen again and this morning it was crusty. So I used a warm washcloth on it and the hook came out in a large glob! I put Terramycin in it and put her in a hospital bin. She's not too happy to be resting. Even worse, I think a mite fell off of her. I couldn't see anything else while inspecting, but I did have an outbreak in October. There was blood on one of her eggs but I thought maybe it was because she hadn't laid in a while. I'm so frustrated. When I realized I had mites, I gave my coop a super cleaning and dipped each bird in a bath of poultry dust, sulphur dust, and sevin. They were not happy with me. But I was hopeful that I would never have mites again. I have been inspecting them regularly and haven't seen anything. Fingers crossed it is a small spider or something. I captured it alive and I'm on the hunt for a microscope!!
