I recently fenced in a small grazing area for my horses, as they have pretty much decimated their pasture and I don't want to start feeding hay just yet. I put strips of yellow flagging tape along all the new fencing as a precaution, because I thought as soon as I let them into it they might start tearing around and run right through it. Today when I let them in they ran a bit, but quickly settled into some serious grazing. As I watched my yearling colt Cody grazing alongside the fence he suddenly lifted his head and tore off a piece of the flagging tape. He still had a mouthful of grass and continued chewing, but before I could get to him he had swallowed the whole works- flagging tape and all. He seemed fine afterward, but should I be alarmed, or will he just pass it through? It wasn't a huge piece- maybe 6 inches long- but is there anything I should watch for over the next day or two?
