I do not know for sure, but I haven't seen anybody say that they do. I skulk around a lot while at work.I also have possum traps set but I catch them all the time. When 1 got into my coop last year he took my only ee at the time and I went to trapping and caught him, but he toar there body up, and left some for me, this time they just disappeared, with only a little hole as a clue. Thanks for all the advice. And, btw, do foxes eat eggs?
