On my farm we have a bunch of chickens. My little dog (terrier) kills our chickens. To be exact she has killed 4 now and we haven't even had her for a year. She gets help from our border collie since he corners them and my terrier goes in for the kill. I'm not really sure what to do. I have researched but nothing helped. I'm scared my terrier is going to try and kill some of our new born kittens or birds. What am I supposed to do?
