Meat chicken tractor turf removal

Give me extra eyes or experience here, I’m a newb with a scheme 😂 we are wanting to raise about 30-40 meat chickens later this summer (likely rangers). I also have a roughly 6,000 square foot lawn of aggressive grass that I’d like to clear and plant cover crop in as a precursor to slowly converting to food forest. I’m picturing a chicken tractor that I move infrequently enough that the chickens kill the lawn, then I move them to the next spot and fill in the cleared spot with thick thick mulching and enough compost on top to plant a cover crop in. Then as I slowly have resources to plant trees and bushes I can plant amidst the cover crop without having to pre-clear grass every time. Thoughts? Anyone do anything like this?

welcome newb with a scheme (the best kind!!)!
You may enjoy looking at Justin Rhodes' youtube channel, where he does a lot with chickens in tractors following his pastured animals to eat bugs and build soil, but he also has a few "static" chicken runs that I could see being similar to what you're thinking.

Am I correct in thinking that your goal is to convert your lawn into something more productive and helpful than grass?

I tried to clear a spot for my garden one year with chickens and it worked... but not as well as I would like. I ended up with a spot devoid of any grass or weeds which is what I wanted, but it took longer than I thought and ended with a hardpan dirt (and probably less healthy conditions for the chickens than I wanted).

My suggestion might be to plan out where I wanted the trees and bushes to go, and then spot mulch, rather than do the entire area. In each spot (or each strip maybe) that you want to put a tree or bush, I would scalp the lawn, lay down cardboard and then cover in woodchips (or some variation). This will help create some good soil to grow in and help keep the weeds/grass down in the area until you can plant what you want.

Meat chickens produce much more poop than layers do and we have had them "burn" sections of soil in areas they slept when they weren't moved daily. The problem will be how to get that effect with even coverage.

I would also want to have a high carbon source handy to cover the areas when they move on.

I don't think meat chicks are as useful as adult layer chickens at actually digging. Most meat birds are just babies - most are harvested by 8 weeks of age.
