Yesterday when I went to let out my cream legbars I found them all dead which was a shock. When I looked closely I could see that 'something' had squeezed in through a very shallow gap under the ark. This morning, when I opened the pophole of another ark and waited for my light sussex to come out- nothing. I stuck my head in the house and was met by a big fat startled liver chestnut MINK next to the dead sussex. I slammed the door shut and fetched my gun, but by the time I got back it had escaped through a small hole that it had chewed through the wooden floor! Concerned that it would come back, I left my other chucks free range so that they could escape, but that damned thing returned before I got back from work and has had another two :-( I really dont think there is anywhere that is mink proof as they squeeze and gnaw so I guess my only option is a trap...anyone else had this?
