I saw something new at lunchtime near our chicken run... looked like a dark otter/weasel-like shape with a slightly bushy tail sort of like a squirrel. Bounded away through the snow, not running but more wide leaping like a dolphin... leap, leap, leap. Was very afraid of me. I was about 60 or 70 feet away and it took off into the cornfield next door and hung out there for a while. I'm guessing it was at least 18 inches long + a tail. My question is this... if this was a mink, do I need to be concerned about it climbing into windows (if they were open) of a coop raised off the ground? What are their climbing/jumping abilities? Floor of the coop is about 18 inches off the ground. Lowest part of windows is about 3 feet off the ground. Coop is built solid like a small house but with windows I open in nice weather. Today the ramp door to the chicken run was closed due to the 14 degree weather so there is no way this thing could get in, but I understand is would be easy for this creature to enter via the ramp. I'm guessing s/he was very hungry to venture this close to a house/people. Thanks all!
