It depends on the weather and what day it is.
If it's raining, I'm out about 20 minutes, door to door. That's feeding the horses, topping off feeders/waterers on 5 coops and doing a quick visual check, and collecting eggs. I hate being out in the rain.
My feeders and waterers are all designed to hold enough for several days, so in theory I could skip days if I need to.
Nice days, on weekends when the boys are home, maybe an hour or so to keep bedding in shape, clean out/bleach waterers, things like that. Most of my bedding is simply adding more shavings or hay this time of year, I'm not cleaning much out until later in spring. I hose out nest boxes and replace with clean hay as needed. My feeders are covered with baffles and hung, so they never really need cleaning, just dumped out and refilled. I have a hose with a sprayer end at the coops, and most of my waterers are open containers that just get topped off, or dumped out and sprayed clean as needed. I do have one large 7 gallon waterer for the large coop that gets bleached every so often as it grows algae. I do go through every couple of weeks and scrape poop off the shelves where birds roost.
