My daughter came back from the barn last night panting, saying she been chased by a white ferret coming out of the feed stall. She was talking about an ermine in his winter white coat with a black tip on his til. I guess I know what got my last guinea hen. I don't know if she just thought he was chasing her, but she said he scurried right toward her, so she just ran. She's a seventeen year old girly-girl. Don't know where she came from. On the one hand, an ermine would definitely take care of the mice in the feed stall, but on the downside, if he's going to chase off the "hired help"...not so good.
