Okay, this is gross. Heard about it but it's not in my rabbit book. My 8 week old bun had a hole in it's side, under the skin was a big, yucky, fat, grey worm like thing. EWWWWWW! I pulled it out and it left a hole that I treated with antibacterial. What the heck was it and how should I continue treating the buns AND are my other buns going to get it? And yes, they were on pasture for a few weeks.
