Weekdays: In the morning, 15 minutes. Top off the dry cat food feeder, let the dogs out, slog out the back door, put on boots, step off the porch, walk 10 steps to the run, open run gate, fill up feed thingie (empty large cottage cheese tub), open covered pen door, fill up hanging feeder, open coop pop door, pick up auxilary waterer (the gravity waterer has sprung a leak, must fix it this weekend) and carry it out of the run to rinse and fill, carry it back into the run and place it inside the covered pen. Greet each chicken by name, individually. Exit the run, hose off the boots, leave them by the back door. Call the dogs back in and tell THEM individually what good boys they are and not to have any canine parties while I'm at work. Finish dressing for work and leave.
In the evening, it's after dark: Let the dogs out, change into boots, yadda yadda minus topping off the feeder, lift the lid to the coop and count chickens quietly, close the coop lid, close the pop door, reverse the process. Top off the dogs' dry food feeder. 5 minutes.
On the weekends, I do the clean up chores, talk to the chickens a lot, watch them do chicken-y things, and couldn't possibly tally the amount of time it takes to complete chores. Too many breaks in between. ;-)
