Good to know - we have a huge amount of ground squirrels and gophers, so maybe that is what he was after. As long as I never catch him after the chickens we are OK.I have these in my yard with chickens for years.... They are very good for controlling small pests, I would never harm or remove them without having a real problem I knew was being caused by them, I would not worry about it. They will eat rodents, like gophers, baby squirrels, lizards, etc. They are beneficial.
