Just make sure it's roomy enough for the little ones to get away. Having a bit of clutter around helps, like boards or a pallet leaning against the wall/fence, wooden boxes on their side, old wooden chairs, that sort of idea. Plus, dual feeders/waterers. I have 7 that are about the same age, with two hens and a rooster in a breeding pen. One hen went broody so I let her sit on 5 eggs to keep her there as she's the "heater" in the hutch as it still gets cold here at night. The rooster doesn't touch them, but the hen pecks if they are where she wants to be. They just run away.
There's two dishes of mash in there which the little ones were hogging, a nipple water bottle on the left, and the nipple bucket on the right.
