We are considering moving our horses, one old chap and four younger horses, to a field that has, for a number of years been arable but has now been seeded to grass. The grass has not been grazed at all and it is still short grass at the moment, I`m not sure when it was seeded but probably last year. How would you move the horses onto new grazing from established grazing where they have been for a number of years. I am worried about colic and laminitis especially the old horse. I`m thinking short turnout to start with - we have stables and they come in at night with hay all year round where we are anyway.. I would like to have 24 turnout during summertime eventually. Is there anything I should be aware of with new grass. thank you for replies!
