Ugh, it's another mystery...I'm starting to think my soil has issues I should test! It again is only affecting a chicken that is recessive genetically.
She came up lame the day before we left for our vacation and when I picked her up, her legs were all swollen and hot to the touch! I brought her in and gave her Enrofloxacin in her water and slathered her legs with vaseline. By Wednesday, her legs were still swollen and also her little comb had ballooned up as well.

She has no other signs of illness or bumblefoot except the weird swelling, so switched her meds to an all in one med--with a percentage of doxycycline, enroflox, ronadazole, and one other thing. I also started applying magnesium oils to her legs instead of vaseline and supplemented her with a mix of oils that help lower uric acid. Trying to cover all the things I could think it might be. The leg swelling is way down and her feet are much cooler, but now have scabs and look like they are healing from sores. The comb hasn't gone down much though and she definitely doesn't feel well. She eats some, drinks some, and sleeps a lot...but she is standing again and last weekend she didn't want to stand at all. Any ideas?
