Thanks for the incites. I am sure it is a weasel or mink. I have delt successfully with coons and possums for many years. I have three callback pens which I stock with 25 birds and they usually last all season. I have Jaggars Quail Funnels in each pen and their design prevents anything but weasels from getting into the pens. Only the last two years have I had this problem. I caught one in a Hav-A-Hart trap last year but haven't caught one since. Any other ideas would be welcome.
