I just dump whatver I have on my compost pile and don't worry about the structure of what I'm adding - but I'm only doing slow/lazy composting. I had very little success getting a fast & hot decomposition process going, so if that's what you're trying to do then throw this post of mine out the window, since I haven't figured out how to sustain the internal heat in my climate yet lol. I mainly just try to control how much pine shavings ends up in there since I don't have a lot of other "green" to add to the mix most of the time.
This is unrelated to anything you asked about, but just want to tack it on just in case: with heat and a lot of flies about, keep an extra close eye out for messy chicken butts and clean them quickly if it happens to minimize the chance of fly strike. It doesn't have to be related to any underlying health problems or illness; hot chickens drink more, more water makes wetter manure, and sometimes a chicken will poo itself by accident and then the mucky feathers situation can snowball rapidly and start to attract the flies.
