Last month we had a single Guinea Hen show up in our yard, which is located in a sub division, here in Central Wisconsin. I started to feed it & am now providing water, that is heated. This Guinea Hen has been roosting in a large pine we have in our yard & also on a ledge under our bedroom windows. My question is, how hardy are Guinea Hens & can they survive a Frigid Wisconsin Winter? Today we have a high of 2 Degrees., with below zero temps at night.
