We have a 10 year old Jack Russell who is very smart, well behaved, but really wants a chicken. SOOOO...that being said, when we built our coop/run we built it thinking so he couldn't dig in. Well...we did a good job, it's been a month, and until now he hasn't gotten in. But today, he did. He has probably been looking for a week now for the weak spot in the fence, and he found it, digging under and getting one of our chicks. He didn't kill it, only wounded it, and we are currently trying to nurse it along. ANYWAY-is there any good ways to teach dogs not to go around the coop? He got in a good bit of trouble today as my mother gave him a little paddle or two on the backside...but other ways/deterrents. I have already added more stakes but I think maybe railroad ties or something all along the outside of the fence will be best, maybe even a strand of barbed wire buried in the ground. Suggestions? Teaching certain things to the dog so he won't do it anymore? I know it is in him since JRT is a hunting dog, but I still have hope.
