MIne ignore the hay in the summer, I assume because there is so much to graze and browse? Winter though I feed it in the sheds, they will pick up large lumps that they drop but the rest kind of ends up as bedding. I use haylage nets, tightly packed, for the unhorned as i find the holes are smaller than the hay nets so a) safer (wouldn't use near kids though) and b) less gets pulled through and wasted.
