How many nesting boxes?

Chrism, I assume your hoop house is fixed and not moved around like a chicken tractor? If it is movable you just move it when you need to. If it is fixed, well 30 hens will strip any green stuff from the floor pretty quickly and they will poop a lot, especially when on the roosts at night. You might have to do some poop management under those roosts. Time will tell.

If your coop floor is pretty dry and they spend most of their daytime out ranging instead of staying in the coop and pooping in there all day, there is a pretty good chance you will not have to do much if anything to manage that poop. If the floor gets wet or if the poop concentration builds up in there you might need to do something. If it is regularly wet you are kind of in a bind anyway unless it drains really well and you have enough ventilation to dry it out pretty quickly. If it stays dry you can usually help yourself a lot by putting some bedding on bare ground to absorb the moisture from the poop and keep it from getting so concentrated it keeps itself wet. Bare ground may work for you with no bedding. Again time will tell.

Some people with little coops clean them out really regularly, maybe weekly. With a coop as big as yours that is something you want to avoid as much as possible. That’s hard work. As long as it doesn’t get and stay wet you should be able to manage that. It’s pretty common for people with large coops to only clean them out once a year in the fall and put that stuff on the garden so by spring it’s broken down and ready to plant. I have a droppings board under my roosts which greatly reduces the amount of poop that stays in the coop and clean mine out about once every four years. That pure poop from the droppings board is great for my compost pile.

A half acre is roughly a 100’ x 200’ area. In your climate that should spread the daytime droppings out enough so you don’t have to manage that. During the growing season that will probably stay green, though you will need to mow it occasionally to cut down the weeds they won’t eat to let the grass grow better. During the winter they will pick it pretty bare but maybe not too bad. Still 30 hens is a lot. When the grass first starts to grow in the spring you might need to keep them off of it for a week or so to let the grass get far enough ahead of them so it will grow. They love those first green sprouts.

We all do it differently. You can find a method that works for you though there may be some trial and error.

I agree. Putting your rough location in your profile so we can see your climate helps a lot in some questions.

Well... on aart's advice, I paid some attention to the ground in my coop.
I tilled the ground a good 4-6 inches deep.
I then topped it with grass clippings, pine chips and lime. I tilled all of that in and then laid another layer of all of my toppings and wetted it without soaking.
I'm looking into the feasibility of encouraging an earthworm workforce in the coop for both aerating the soil and food for the birds.
I'll continue to add my grass clipping and turn it weekly and till it a few times a year as long as the ground isn't frozen.

My plan now is to do this for a couple of years and then build a new coop elsewhere and use this spot for growing vegetables.

BTW someone mentioned using "fake eggs" in nesting boxes. I tried all kinds of ways to break my hens of a bad habit.....breaking and eating eggs. I could not figure out who the culprit was. I placed 1 fake egg in each nesting box. Bingo! It did the trick. No more broken eggs. I guess hitting a beak against a fake egg was not pleasant. And they look so real I used a Sharpie pen to place an X on the fake eggs so we could tell them from the real ones!

My girls stay in a hoop house that moves around. We have to move it about once a week around our yard with our truck. My 21 girls and 2 boys are free ranged and they are only in their coop at night.
