You are NOT annoying, questions are awesome! Here is MHO:
off the ground is a choice, really. My "coop" is at ground level, all of them. As long as they are critter proof, its ok.
Height is also a preference. I like being able to walk in, so all of mine are 8ft but they are sheds with runs and pop doors.
I am in central IN, and no insulation. Really depends on your breed of birds.
Ventilation, MORE is better, but you don't want draft in cold weather. So up high is important, but windows won't hurt either.
Run height is also a preference, I like walk in runs. But if its just for chicken use only 2 ft isn't bad, 4 ft is better.
I was thinking off the ground because we are LAZY people...
We've only got a little corner plot in an addition in Bloomington, so space is limited. I was thinking 4'x4' and 3' tall box kind of thing for the hens to roost in (nesting boxes jutting out from the side). And every opening covered in hardware cloth.
The run only being 2' tall was to save on hardware cloth (we're CHEAP too...). I was thinking of making the roof secure but detachable for cleaning the run out. Hinged on one side and padlocked on the other. Flip the lid and rake it out kind of thing.
For breeds, we though that starting with 2 rhode island reds and two orpingtons to start with, maybe get a fancy bird next year...
Is it possible to get hens that are socialized and ready for the coop, or is that just pie in the sky?
Thanks for the prompt response!
