The only time I have had a rat get the bait off the trap (neck breaking snap traps,) and not set it off I was using creamy peanutbutter. I switched to chunky since the chunks will wedge into the bait holder and they have to work the trap harder to get it all. That solved the problem.
The Jack Russell Terriers and Rat Terriers love to do their job and are very good at it. You can put them in a hay barn and they will work themselves silly. However, they may go after other small animals as well if not used to coexisting with cats, chickens (especially young ones,) and such. I think any dog will work out best with other livestock if it is raised with them and given firm and intelligent training. As will all Terriers they have the attitude of, "I know my job--Now leave me alone and let me do it." Some basic obedience training is worth the effort before you turn them loose.
I liked the idea above about the 3" pvc trap since the rats and mice can get to the poison and the chickens can't.
I am also partial to a .22 LR rifle. That will cure the ones who walk out and stare at you.
Try "Just One Bite" or a similar poison. I have read that rats will eat a small amount of something new to them and wait to see if it makes them sick before they continue. Just One Bite would seem to address this behavior with lethal results.
