Hi, since there are so many horse owners on here, I thought I'd ask you all a question that's been bugging me. I have 2 horses, one 12 yr old and one somewhere between 17 and 30. They get free choice 2nd cut hay. I pay $4. bale. It's good stuff, usually, but I throw away alot. These horses both had colic at least twice last year before I switched to this new hay. Since then they've been fine. I may just be paranoid now, but I figure throwing away 10 bales is still cheaper than a $200. vet bill. I had a new barn built this fall and we put hay up in the hay mow. We set it directly on the floor. I didn't think then, but the wood was probably somewhat green and perhaps damp. Now every bale that was touching the floor has a white dust when I break the bale. I would definately not give it to the horses as is. The hay itself still looks nice and green. Question is...Can I rinse the hay off and feed it to them? Knowing that they've been sensitive to something in the past (perhaps the other guys hay). I hate to keep throwing away all these bales. Is it too risky? I've had bales that were moldy before, but they were brown and stiff and smelled bad. These just have white dust..??
