Apologies! Let me doodle what I mean.

So I want the walls of the run to be 6ft, with an angled roof for additional headroom. The back side will be along a wood panel fence. The right side is where the coop will be located and will be mostly solid (except a 2ft high section at the bottom).
And yes, the coop will be built before we get any chicks regardless. I will be building it next month and we were planning on ordering chicks for the end of August at the earliest. I was saying that I could also just wait until next May.
Brooding them outside would be lovely. We don’t have a garage so they usually end up in my office - at least that’s what we did with the quail when we had them. Not my favorite arrangement and very smelly!
