Thanks everyone for the advice!
Like most have you have said, we have thought of x-rays, but like Cat pointed out, this horse isn't ours, and I don't personally want to put that big of an investment into this horse immediately. I know it sounds mean, but I'm being realistic.
I have my farrier coming out this weekend and will get his professional opinion on Stormy. We're gonna at least try and get him trimmed, and then get him up on a float to a chiro. Obviously if he's gonna be unsound and sore quite a lot, we're gonna try and just find him a 'pet/paddock mate' home, if the landowners really want him off the property... so far they don't seem that fazed as long as he's not being a nuisance.
I'll let you all know what the farrier says :)
Thanks again for the advice!
