Mine are out 24/7 when the weather's good, although the TB has decided he's a house horse and would like to be in most of the time, thank you!
I get up at 5:30 a.m., let the dog out, and go get the horses' feed tubs from their stalls. After I measure out the horse feed and wet it down to soak, I give the cats their breakfast.
The TB goes into a stall, because I have to feed him separately from the other two. He gets a lot more than the Arabians, and it's a different ratio.
The other two go out into the front paddock with their food. I take a wheelbarrow full of hay out with their food, but don't distribute it.
The dog and I go back in the house where I feed/water her, and then I make the bed, brush my teeth, get my lunch ready, and do a few chores.
Once all that's finished I go back outside, distribute the hay into piles, grab the TB's halter/lead line, and the two Arabians' now empty feed tubs.
I put the feed tubs and wheelbarrow in the barn, and close it up for the day.
The TB goes out with the Arabians, and I hook his halter and lead line onto the gate with the Arabian halters/lead lines.
Once all that is finished, I go back inside and do my hair and get dressed for work.
It takes 40-45 minutes to get to work, and I have to be there by 8:30 a.m., so I need to leave no later than 7:45 a.m.
When I get home in the evenings, the horses are let out of the front paddock into the grass pasture, and I start the feeding/watering routines all over again, with the exception that the horses are all stalled for their evening meals.
Once they're finished, they go out on grass at night. During the summer they only get hay in the morning, or when they're in their stalls because of bad weather.
I fill the water troughs up at night, so the only animals I have to give fresh water to in the morning are the dog and cats.
None of this includes mucking, boo-boo treatment, general barn cleaning, or horse grooming. Those are relegated to evenings and weekends.
