Lost my 3rd chick in 2 days. This time I found the body inside coup with legs and guts eatin. Its ate a couple eggs too . At first I thought it might be the 4 week old chick going through fence and dig up getting them but now with body found I know its a predator I need to trap. I've never had a problem in 2 years. What could it be? What's best bait for trap. Its hasn't messed with any big birds or my 8 week old chicks.
