I just got off work and came out to collect eggs and check on the chickens and I was surprised to find a big turd in the coop. I cleaned it up and looked around. I spotted a possum curled up in a corner by the nesting boxes nursing babies. Oh my goodness! I thought I had a secure run. She must've come in this morning when the door opened. I have no idea what to do at this point. Any suggestions are welcome. Please!
