We would like to do broilers in our horse pasture (we have 23 acres of horse pasture that we would like to add manure and compost to). WE'D like to kill 2 birds with 1 stone but prefer that the flying predators don't. I read that a narrow run will deter hawks, owls, etc, etc. Does anyone have experience with this? Our plan is to create a 2 panel shelter out of cattle guards and have electric netting in a long narrow run that we move frequently. Any experience with this plan? Bad idea? We really don't want to do tractors.
