You have to make shure your coops are very sturdy I know some people that use concreat or bury the wire partly under so animals cant dig under , only let them range while someone can be there to watch them , get a guard animal of some sort some breeds like great pyrnese (spelling) are good with that some times heck a pair of big old geese might be a good deternant lmao if you have ever seen someone attacked by them, I saw a guard camel one time with a farmer that had small goats =P. There is a section for preditor control have you looked at it?
