Coop cleaning may mean many different things to different people, so you may get all kinds of good sound advice on this subject.
Basically, depending on the number of chicks you have and the size of your coop, would most likely indicate to you how much and how often does your coop need cleaning. The more chickens you have, the more often you need to clean. Basically you don't want your chickens to be stepping over a layer of excrement or urine. Let me give you an example of what I do, this may or may not work for you as I said based on your personal situation.
I have 2 coops (one large coop with 8 nesting boxes and one smaller with 6 nests).
In the summer the chickens go to sleep in both and lay eggs and other than that they don't spend any more time in the coop, they spend most of their time outside the coop in the run or free ranging. In the winter they stay a lot longer in the coops and also sleep tidier longer. I used pine wood shavings on my coops and nests.
In the summer I check the coops for excrement accumulation, every 2 days or so and smell around to sense urine intensity. After about 4 years I kind of have it to a science for my flock size and coops size ( around 30 adult birds). I change their whole pine shavings every other week and clean the coop, like really deep clean (vinegar and other cleaning stuff every 1-2 months). In the summer I clean the shavings and use scalex spray in the coop inside (due to mites and lice, that is the season for them to invade your coops). Even though I have a kind of schedule, I always check and sometimes replace the nesting and shaving a little more often than 2 weeks. You can see excrement, but you cannot see urine, that is why I keep checking. If it starts to smell and there is not a whole lot of excrement (poo) on the coop floor, I go ahead and clean and replace.
For regular cleaning I remove the shavings, hose down the coops with a hose full pressure. Let it dry. If a full cleaning is due, I spray vinegar on the walls and celling, let it dry and then put new shavings (nice thickly laid). If a regular cleaning, I remove the shavings and any excrement that may have stuck other than the shavings. Check for bugs or any unusual changes, if I see bugs I spray with scalex and let it dry, then add shavings. If no bugs, just put new shavings and done it is. Your hens may or may not like the cleaning time. Some of mine go as far from the coop and some are right there with me. If they are present with me, then I am extremely careful with the cleaning stuff as I don't want them to inhale any foreign substance. Hope it helps.
