It is confusing because we keep chickens in so many different ways in so many different condtions that no one answer can be right for everyone. Some people keep a few hens in very tight quarters in the middle of town. Some have much larger mixed flocks out in the country where space and neighbors are not a problem. Some keep them as pampered pets while some treat them as livestock. Some people have chickens perched on their shoulder while they are chatting on this forum, while others would throw a fit if they saw a chicken in their house. I'm in that last group, by the way.
I haven't cleaned my coop bedding out in three years and I've never wiped the roosts down with bleach. I do occasionally remove piles of poop when it starts to get too thick under the roosts. Occasionally. But mine don't spend much time in the coop. They are out eating grass and chasing bugs. My coop is well oversized for the number of chickens I have so I have to work less than someone that shoehorns their chickens in a tiny space. There are a lot of people on this forum that do things a lot different than I do.
I see by your signature line that you have a pretty good sized flock. If you can tell us a bit about the size of your facilities and how you manage your chickens, somebody might be able to give you some more specific ideas, but my coop will get cleaned out when it starts to stink or this fall, whichever happens first. It's time to put that bedding in the garden and start over.
You don't need to keep everything sanitized. I think chickens are healthier when they are allowed to build up immunities to what is in their environment. A wet coop is a dangerous possibly disease-ridden space, so try to keep it dry. It will probably stink if it gets wet. If it is not stinking, you are probably OK.
You'll find a lot of people use a lot of different things in the nest boxes and on the coop floor. None of them are right or wrong, just what we use. My preference is straw or long grass cuttings in the nests and wood shavings on the coop floor. I don't like straw on a coop floor. I mucked out too many stables and barns in my youth and that straw can mat together and make it a bit hard to clean out once I decide to actually clean it out, but plenty of people use straw. It's just personal preference. What you're doing sounds fine to me, but I don't know your specific cirumstances. If ground corn cobs are cheap and available, that sounds pretty good to me for the coop floor. I prefer something a little more substantial in the nests though. I like the way straw or grass holds its shape.
