Yep, looks similar to the one's we have, ours gray to brown color, tiny fast little buggers. I know they are around, but none in the coop so far
I'm a night person, so last winter I thought I saw a huge rat in an outdoor bird feeder (different area from the coop), got my rifle and was going to dispatch it. It didn't run and just kept eating, I got really close, kept eating WHAT THE HECK!?!
A flying squirrel
