Kristip, I built a wood 2 x 4 structure inside the coop that is free standing. It does secure to the coop walls with large diameter wood screws, but that is only to keep the wood structure and the coop together. I screwed the wood walls to the floor and to the steel rafters for security, and it makes the whole structure stronger. I built the roosts out of 2 x 4's cutting off the two outer edges, and put 2 inch chicken wire on the bottom to keep the hens from wandering in the poop, then added poop trays which slide out for cleaning. they are simple oil drip pans from the local automotive parts store for about $10 each that I clean weekly. So I have three of those under the three roosts for the 15 hens. Under the poop trays are the nesting boxes.
I use 60% of the space for the hens, 40% for grain, feed and pine shavings. There are sky lites in the ceiling I open for ventilation in the summer, plus, I placed the whole thing on a wood subfloor for stability. I put some eye screws down in the wood frame behind each door and use stretchy bungee cords to hold the doors open in the summer to provide extra ventilation.
I added an automatic door that opens in the AM and shuts in the PM, it took a few tries to get the hens used to bedtime. The tries were for me setting the timer correctly, not for them, they knew when it was time to go to bed
