we came out one morning to find that one of my chicks had its wing ripped off. there was no trace of feathers anywhere (believe me i looked). and there was a small hole in the fence, but no fur and it wasn't pushed apart. i then started putting my chicks inside a box at night and letting them out in the morning. we then set up a small trap (all we could borrow) and the first night we caught a dark brown domestic cat. but im thinking if it were a cat i would have found feathers somewhere. we did reset the trap but haven't caught anything else but the fence has been getting pushed in and there was some light gray kinky hairs caught on it. i have heard possums will eat feathers a bone. i'm thinking the trap is too small for a raccon or possum, so we would never catch them if they are predator. what do you think it could be?
