Nancy have you tried using an open can of tuna fish in your trap? I had a raccoon eat three of my chickens then I got a big trap used for foxes and raccoons open up a can of tuna put it in the back. The next morning I had a big raccoon in it, shot it and buried it. No more problems until the chicken hawk showed up. Put up bird netting over the top of the run, one hawk came in and I had to shoot it and bury it with the chicken.
