How terrible Kim!!! You have had your fair share of predators and I sure hope you get what keeps coming back. You have had enough losses! We recently had a skunk trying to get into our chick coop (old shoulda been burned coop lol) and we caught it using a humane trap with cat food. So far I have seen no evidence of it or anything else coming by- but I know it could happen. I am always on the lookout! I constantly remind my husband that it does not hurt to be overly protective and build anything sturdy enough to keep all kinds of critters out. Just because it hasn't happened, doesn't mean it won't. And once they learn where to find food (or sometimes a place for just a killing spree.......) they keep coming back. I really do hope that you and your hubby get it all taken care of. It is worth all the extra work in protecting them.
