And found you guys. I'm a guy near Charlotte N.C. that has been researching feeding round bales to horses for a long time. Our N.C. Horse News board has a big thread about a teen whose horse died this week because his halter was caught on a hay ring and he flipped backwards with it and suffered a neck injury evidently. Would you tell me of any injuries you are aware of ? And I saw a post about the O'Neil Feeder, I would like to hear more about it. The inventor cited my original feeder design in his patent as prior art. ( I am not selling feeders right now , I am between manufacturers ). Have any of you heard of the hay tunnel ? Hi from N.C.
