@catinthecoop here is my prefab coop:

The inside is about 4' x 6'
I have never wetted down Equine Fresh. Some time after I was regularly using it I read THEIR instructions. They also recommend 8 bags/horse stall and I guess they think that it would hurt your poor horse, "Fluffy" put down straight. I do not like to waste bedding, so I only use it where my horses pee. My 3 horses have their own pee and poo spots in their stalls and as You know, you do Not have to completely strip a stall OR a coop if you keep up with them.
For my two geldings I use two bags in their pee spot and I cover with either yesterday's shavings in the stall or straw, and I only use one bag for my mare. My stalls are odd shaped, 10 x 13, 12 x 12 and 10 x 12 bc I created them in my barn which only had 1 wooden stall wall to use. I bought round pen pieces including two round pen gate panels and one 13' gate. It started sagging so I added a gate wheel to it.

I use Equine Fresh as the first layer under my chicken's roost boards, then I dump Medium Pine Shavings in the middle of the coop floor, which I added a piece of vinyl floor to when I assembled it, to keep the wooden floor from wearing out too early. There used to be posts here with tips like that, but this site is so busy that it might be a little harder to find them than when I joined in 2009.
You ALSO know the animals will spread it out so you don't have to waste any time doing that yourself. My chickens end up covering up the pellets themselves, but if you check the next day and they haven't you can spread it out yourself. I like the floor covered with bedding and sometimes my hens lay a clutch of eggs on the bedding instead of their nest boxes.
I used to do CW Reenacting and I met a reenactor who spent a summer mucking stalls at a training facility. He and another worker had to clean 50 stalls/day and one would muck out while the other did the bedding. He said that it took 20 minutes/stall. This was before I had my own place so I listened when he said that they dumped the bedding in one stall and moved on. Horses pace and move around their stalls. Chickens dig and scratch. Both of them use their natural behavior and help us save time in our day.
