Brandy is not too keen on the sulphur, it makes her pull faces and spit. I try it on Baileys first who is about half her size and Brandy tolerates about one fifth of what I put in his food. Talk about being fussy. She loves the hay, chaff, oats and copra. She’ll pull up her nose if I put as much as a smidgen of anything else in it. So, yes, I’m still working on that and figuring out the amounts because I rather keep the flies off her by putting stuff in her feed than continue to put brut on her.
