I love this last idea-so perfect!!! I have a hay net and it's the biggest pain to hang high enough for safety (I'm only 5' tall)....This, however, is a great idea, and I have a spare trough just that size! "Wow, I could've had a V-8!" :)
I've seen the nibble net before! I think we may just cut a rain barrel or something in half, then cut some wood for the top and cut holes in that, and then on the other half do the same but just make a bottom
What people aren't keeping in mind is that a horse's jaw is designed to eat at ground level. As the horse lowers it's head, it's lower jawbone moves into "dining" position. A hay net can touch the ground if the area is clean or covered.
Saddlebag, I do agree with the idea of ground level feeding and there are nibblenets than can be put on the ground.
We have so much sand here that that is why I don't actually feed hay directly off the ground... Yes, we use a sandclear product... I have our nibblenet attached to a fence and it ends just an inch or so above the ground. As our horse eats, the hay moves down and he is forced to follow it (down) to get his forage.
