Wow Lindypie, Welcome to BYC forum.
Three is a nice number.
Some of the process you follow will depend upon the type of coop you have. IF you have one that has a poop-tray, poop boards or removable floor, your task will be quick and easy.
What I usually do is put pine shavings on the pull-out poop tray...You can get a big bale of them wrapped in plastic and compressed at a feed store, or
TSC, I believe. I pull out the trays on a daily basis then with two kitty-litter scoops, and pick up the droppings to deposit in a plastic tub. When the tub is filled enough, I put it in the compost.
other folks follow the 'deep litter method'. Usually that will apply to bigger coops and more chickens.
You can patrol your yard now and then for droppings that are in walkways with the two kitty-litter scoop method.
Now and then dump the whole poop tray into the compost, and start with fresh litter (pine shavings).
When it is messy wash the poop tray and allow to dry before replacing.
Wash waterers daily and refill or as needed, same with feeders----
When needed or at least twice per year clean the coop throughly. (if it is wood you may need to repaint and to re-finish surfaces). It can be as simple or complex as you like---but that is one easy approach. HTH
