OK - this is what I did: I put her in a basin of warm water. She was calm and then would freak out and then was calm again, and so on. I couldn't really clean her dirty bum feathers because she was struggling and I needed both hands. But while she was struggling, she pooped (looked healthy). I blew her dry (she liked that) and I sprayed the Vetericyn on the area. Then, with a glove, I tried to push it in. I couldn't tell if it was in. But then some of it popped out again. I honestly have no idea what I'm doing. Any thoughts about what I should do next? Here are pics from when I thought I pushed it in, to after.
