Just after breakfast, we discovered an Ermine (weasel) in our house! Instantly afraid it would be lost in our house, we quickly opened the door and chased it outside, where it ran away. Now, I am worried about my chickens. My coop is not weasel proof. I can't see how it ever could be either. This weasel has been around for years we think, we have seen it around, and footprints on the snow. Does this little weasel breed also kill chickens? It seemed so tiny. We are going to try to trap it.
