I tend to get disappointed looks and some kicking at stall doors, but that’s about it
If your horse is in a routine, try to feed him around the same time.
It's fine if you can't give food to the horses every day at the same exact time, but try not to be very late! Horses like routines, they like to eat at the same time every day! They kinda know what time it is so they will let you know when it's time to feed them (kicking doors, pawing and calling it's their best way to do it)
Hope it helps
It won't change anything physically but as Liz was saying, he will be waiting for you and ask for food!
Don't feed your horse just before you ride him because it is not good for his work then.
Horses have rituals just like us but if you're a little late it's not a problem, he will be happy to eat anyway ;)
You’ll have one upset horse
