The grassy pasture has fescue in it. I have heard that if you turn your horses out on fescue after it has frosted, they will get sick from it (colic) or get foundered.
These horses I have are right now on a mainly dirt lot, and they were on a dirt lot at the place they were before I bought them.
My question is:
Will fescue hurt the horses? If it has frosted over, will it make them founder or colic?
If it will, when will it be safe to turn them out on it?
And how should I transition my horses from a dirt lot to a grassy pasture? Should I turn them out for only an hour a day and slowly work my way up to 24/7? Or what?
Any help would be wonderful.
