Livestock and Fencing Products
Electric Fencer
We use this electric fencer for our pigs. Our old one shorted out while we were out of town and fortunately, our neighbors had one to loan us until we could get this one (and they put our pigs up for us, they're pretty awesome)
Water Stock Tank Heater
This is the exact model we have for our cattle and have used it for years without a problem. This model works best in a metal tub, not a plastic one.
Water Stock Tank Heater with Guard
This model has a guard on it if you have a plastic water tank.
Heated Water Bowl
This is a heated water bowl many people will use for smaller livestock like chickens.
All-in-One Home Butchering Kit
Home Processing Kit
