I recently bought a slow feed net for round bales. So far so good except I keep repairing it. Has anyone used this in winter?? If I don't use it my 2 geldings will eat a 1300lbs round bale in 1 week. When I use the net it lasts close to 2-3 weeks. I also use slow feed bags to hang in the trees and the horses seem to prefer them over a pile on the ground. Does anyone else have opinions on these nets?
