these aren’t the best pictures and they were kind of random under construction ones but this is basically some of it. Sorry it’s dark out or I would take better ones.
That's a good amount of run space to work with. Here's some pointers on how to fill it up with clutter when it comes time to integrate! https://www.backyardchickens.com/threads/a-cluttered-run.1323792/
For the time being plan on having the adults see (but not touch) the chicks in their little coops for at least a good week, if not two or more. Actually from looking at your fencing, you may need to hold off until the chicks are large enough that they can't pop through the fence, or you'll need to reinforce the fence with smaller opening mesh - I have chain link and a split run and the chicks were going under the diamond shaped openings between the two halves of the run up until 8 weeks or so.
