I am so sorry for the loss of your flock. That must have been horrible!
I'm with the others. Where those predators came from (no matter what kind they were) there are more, and behind those even more. It's a loosing battle to try to eliminate predators when you live in the country. Your best bet, in my opinion, is like the others here have said, build a very strong coop and run. Then you can rest easy knowing when the next inevitable batch of hungry wildlife finds your place, they will have to move on for their meal and your chickens will remain safe. (My two dogs and a very strong coop protected our flock just this morning form a raccoon we watched them chase off!)
