Converting Shed Into Coop

I just recently purchased a shed to convert into a chicken coop. It's an 8x12 so I hope to house the majority of my flock in it. It comes with one large human door, a window and ventilation at the very top on both sides. I have several questions as I will need to make some modifications:

1. I'd like to paint over the treated wood for easier clean up, and to help prolong the life of said building, but which type of paint do I use or is there a better option?

2. What nesting boxes do you use, that are fairly cheap, but great quality? I don't want to cut a giant hole in the building so nesting boxes that protrude from the building is out of the question.

3. Do you prefer sand, coffee grinds, shavings etc. and why? I have sand in my runs currently but use shavings in the coops.

4. How many feet of roosting bar space do I need? It's an 8x12 building, so 4sqft per bird would be up to 24 chickens. My flock is currently at 48 +/- and most are still in brooders but 20 are outside in coops already. However, if I free range my chickens, does sqft really even matter if I have enough roosting bar space?

I think that's it for now. Thank you for reading and giving me your advice.
 
Firstly - I bet you will need a lot more ventilation. Aim for 1 square foot of permanently-open ventilation per bird far from the roosts. Sometimes even more is necessary in warm climates. Adding your location to your profile can help us better help you.

There are a lot of threads on this very topic. It all depends on YOUR preferences, climate, type of coop, how much time the birds spend in the coop, the amount and type of birds you have, and what is available in your area. The best thing to do is try out the different types of bedding that are readily available to you and choose the one that best fits your needs.

1 linear foot of roost per bird. Yes, square footage of the floor matters since the coop will be used by the birds in inclement weather, if the chickens are up before the door opens, during feeding time, etc.

We used liquid rubber from lows... i cant remember the exact name but its holding up very well we did 2 thick coats.... used 5 gallons on same size as yours...
48 might be a tad crowded but i think youd still be ok. especially in winter will keep coop warm

How Much Roost Space Do My Chickens Need?

Chickens need approximately 8-10 inches of roosting space per bird. Larger breeds may require closer to 12 inches per bird. Providing adequate roosting space is crucial to prevent overcrowding and related health and behavioral issues.

It rolled very easily on a clean wood floor. I took big goops with roller and spread it out it rolled on good. I did two coats.
i asked my son...he remembered... it was 50 bucks for 5 gallons... put down on new 1 in plywood floor and 6 in up sidewall

i think id put 2 boards the 12 ft way on each side first one foot down from eave and next one 2 ft.. that would give ya 48 linear footand still leave ya floor space open they will fly up there i have a roost built but they dont use it... its lower but my old grainery has some 1/2 steel rods across up near the top... goofy chickens fly up there and clamp there toes around the rod they like to be as high as they can get
 
i see your avitar is silkys... if ya have them or some smaller breeds ya dont need that much roost bars.... that 1 ft for large birds is great plenty... id say 10 in even for large birds
