HELP!!!!

I had two guineas that were killed last night and one that was injured from last night as well and today my goose went missing without any feathers blood or anything at all! I spent two hours with a flash light outside searching for any signs such as blood, feathers, body parts, etc. but I can't find anything and it seems as though the goose disappeared without a trace. I have not identified the culprit who killed the guineas and possibly the goose, yet but I narrowed it down to coyote, fox, opossum, and raccoon. Is it possible for a 20lb+ goose to be killed and/or dragged off without even a feather left behind! The guineas were dragged maybe 20 yards from where they were killed then eaten and the.dragged a couple more feet and then were finished off and there were feather trails, clumps of skin, etc. from were they were killed to were they were dragged to.
