It looks like you've already got a lot of great advice! I can confirm that Basenjis will kill prey. A deer got into my dad's orchard years ago, and my first B, Bell, killed it by chasing it down and jumping up and grabbing onto its throat - repeated three times until she did mortal damage. It's in their genes, and there's plenty of ancient Egyptian art showing just that.
We have a farmer nearby that raises sheep, and feels no remorse in shooting any dog that get's in to chase his sheep around - it's happened several times already. I don't imagine that the farmers in your area are much different - their livestock is their livelihood, so they get a tad defensive!
