My 3 month Polish hen evidently got attacked by a predator last night and was able to bite off his foot and lower leg. She also has some wing damage, but I'm not worried about that. I found her this morning in her A-Frame house inside my larger chicken pen. She is alive and alert! But I noticed she was sitting on the ground and was eating the food around her that I threw to her. ***See pic. She has a lot of mud/dirt around the wound and it's pretty raw but not bleeding. What is the best 1st Aid to give her? Do I clean off all of the mud? What else? I brought her inside the house where I can monitor her now Thanks in advance for everyone's advice!
