How to introduce horse to the grass
Spring is coming and grass is coming too. :) My horse will probably go for training in May and they let them go to pasture for the day (8 hours or so). I don't have grass in my main field, but couple small "grassy" fields I let my horses go in Spring/Summer/Fall (I didn't start it yet as it's too cold and not much grass :( ). How can I gradually introduce her to the grass, so would be no side effects (such as founder or so)?
