Still failing to understand all the micromanagement.
I've kept chickens 15 years this way and have only once had a contagious sickness (a chicken cold) and on average lose a chicken (usually age 6 and up) to an illness every 2-3 years or so (I usually keep around 20 at a time, with many reaching age 12). All I do is a sprinkle some more shavings or straw every week and a once a year compost removal so we don't start bumping our head on the ceiling from all the increased composted shavings underfeet. Part of my success with this method might be our climate (heavy humidity, cool) but surprised I haven't seen other people in my climes posting they do the same.
That's it. That's all. I can't believe some people have to clean their runs too

Wow, what a time sink! And I can take pictures of my runs and coop floor-- they are rather clean. I was just out there sitting in the shavings in my coop and didn't get any unpleasant surprises doing so. Dirt floors work wonders, as long as you have really good hardware cloth dug in and bent in around the edges of the coop to prevent digging critters. Would never go back to a floored coop again, where too much composting=rotting floorboards and we actually had a skunk move in under the coop.
