It's a "Chicken Tractor"
One side
The other side
The base theory is it is a chicken coop that can be
moved around to various spots on the lawn.
The chicken filth will fetilize the lawn as it's moved around,
and, the chicken get fresh bedding with each move.
There are nest boxes lineing each short side, with hinges
to open up and, get the eggs.
There is that green indoor/outdoor matting in each box so
they can be pulled out and sprayed off.
If you have never had fresh eggs, you don't
know what your missing.
The downside of this is that you still have to use feed.
(which is still way cheaper than eggs these days)
OTOH, if you let them out during the day and, then, close them back
in during the night, there is only minor feeding involved.
For the record, we own

Mrs Goon made the whole thing out of about 30% new materiel and, 70%
scrap stuff we had laying around.
Oh..and "Hershey" our rescue dog that has found a home gaurding "his" chickens.
