A possum got in my coop tonight. I didn't even know it was still there. My 3 chickens were scattered across the yard but I saw no sign of anything. I called my Boxer, which btw is the best chicken protective breed ever. And she ran into the coop which is small and can barely fit my 3 comfortably. There was growling and the whole shook. Then she ran out. I promptly shut the door and my husband lifted the roof. My dog had done a number on it, but it was still alive. My husband shot it 3 times before it died. Its still in the coop. DH wants to make sure its fully dead before handling it since its raining and dark out. So, it appears only my roo was attacked. He's a pure Brahma and has so many feathers. He was definitely in shock, didn't even react to my dog licking him. I took him side and he was perfect while I looked through his feathers. He has a puncture/slight tear near his tail. I couldn't find anything else. I kinda pulled it open and flushed it really well with antiseptic wash and slathered it in neosporin. I have Penn C from my injured chicken last year. How long is it good for? Do you think he needs it? She died during my injection (she had a hole under her wing and bones were exposed for 3 days but I missed it when I was looking). I dont' want to do it again if I don't have to. Also, how do I disinfect the coop after the possum has been removed? They're all in the pool shed with my 5 week old. I really hope they don't kill them. Soooo much stress.
