We did it last year with no health repercussions, and dad just tells me to quit worrying, but I am indeed worried that with this sudden burst of new, plentiful grass, the horses could founder.
The corner is roughly a half-acre to an acre in size and from corner to corner is full of grasses and plants that are at least waist height if not higher. They're all pond/swampy, tall grasses too, if that makes any difference. There are three horses going out on it.
Do you think founder is a risk? Nobody did last year when they were out there, and they all went out this spring onto suddenly green and lush paddocks, but I'm always worried and would rather be safe than sorry.
