Please can I have some advice? After a nightmare winter last year with 3 ponies stabled, I've rented a 5 acre field and the 3 ponies are going to have to live out. There are plenty of thick, tall hedges and trees but no field shelter. I'm planning to rug them but not sure how many I'll need or what my routine should be. I remember a thread about some plastic hay feeding devices - a sort of pyramid design maybe but I can't remember the name??
