Hay nets are ubiquitous. We use them in our trailers, show stalls, and regular stall. Anywhere there's a horse, a hay net of some type is bound to be nearby. I used Freedom Feeder hay nets for quite a while, for both horses. When I moved to the ranch, I tossed the nets I had left - they were pretty worn out anyway, and went with the feeding containers at the ranch.
I am thinking of going back to a Freedom Feeder for Izzy, if it's okay with the ranch owner since she's the one who feeds. Izzy eats primarily grass hay which would be easy to load. My hope would be that less would get shoved out of his feeder onto the ground. He scatters the grass hay as he looks for the tiny bit of alfalfa that he gets. He's also bit of a pig so he poops practically in his feeder which means the whole area gets a bit nasty.
I've had a hay net tied to the little trailer where I tack up, and both boys really enjoy grazing from it while they wait. I load the hay net with a flake of alfalfa for Izzy and grass hay for Speedy. Both horses have learned how to push the net around until the "flavor" they like is in front of them. This net is a little big though so it stretches nearly to the ground. The hay also gets wedge in so tightly that it makes eating a slower process than is ideal.
In an effort to make eating a bit easier, I untied the hay net and tossed it on the ground. Both horses took to it immediately. Speedy seems to appreciate munching while spending time with me - sometimes that much adoration can get annoying, but whatever. I've also found that Izzy is WAY more relaxed eating this way than when the net is hanging. I am sure it has something to do with the whole head down equals relaxation thing. And no worries about entanglement; I'm puttering close by so neither horse is actually unattended. I also hang the net back up when I am done.
And of course, nothing gets done without first getting Speedy's approval. Given his recent attitude - more on that in another post, he may be getting a Freedom Feeder, too. They keep us thinking all the time, don't they?
