Can I Put My Chicks Here?

[Chickaroo!]

I have 6, 9wk old chicks. During the day, I let my big girls free range and put the chicks in the run. At night, I have to put the chicks back in the brooder (in my house) because my current coop is to small for everyone and the new coop is not complete.
Anyway, can I let my chicks just sleep in the new coop?

You can see what's done so far on the new coop here:

Obviously I'd pick up the stuff that's on the floor and put shavings down.

I would be a little concerned about lack of ventilation, but otherwise I don't see a problem.

For the size of your new coop, I don't think you need to worry about over night ventilation if it is only the youngsters!

I would only put the chicks in there, not the big girls. They haven't had time to get to know each other yet and I'd be worried they babies would get pecked to badly.
