Ours always have hay or hayledge to nibble on throughout the day and night. As for granules - do you mean like hard feed or chop? Ours get breakfast because they have supplements. And my old mare gets a lot of different mashes at night to keep her going as she has poor teeth. So breakfast and evening feeds for ours. Most of the people when I was on a yard fed breakfast, even just a token gesture. I guess it depends on routine and what they are needing nutrition wise. They do like routine though. I remember being mortified one time because Storm didn't have her breakfast ready. Fortunately for me, the yard had given her a helping of Happy Hoof because I had forgotten to leave it out for her.
