Haven't heard of beet pulp. I'll ask at the stock feeds. Hay is a no go - he just won't eat it. Never has. Would go for the grains that fell out of it and leave the bulk. We went away a couple of months back and I forked out $22 bucks for a bale of Lucerne to keep him going while we were away. Came home and it was untouched, cheeky bugger. Lots of grass at the moment - I don't think we'd have much luck with seed given the amount of rabbits we have here. They're devouring everything. He doesn't have much in the way of teeth anymore - we water down his gumnuts so they're soft but I was watching him graze tonight on grass and he seemed to be grabbing mouthfuls without any issues. Grass is quite long so it's probably making it easier.

He's so fussy, makes things hard. Our other horse ate everything and anything which has it's own problems!
