How Feathered Should They Be Before Moving Outside?

[Flockincrazy]

I started a different thread asking if these two groups would integrate ok after separation until the bantams were old enough...so, would that be possible? Would they completely un-integrate within 1-2 weeks if I separated the standards from the bantams and silkies?

As long as integrated properly they will be fine look and not touch is the best way I've done

I'd have the big ones outdoors with a heat lamp available if it's going to be in the 30's at night, and keep the little ones indoors in the brooder until they're fully feathered.
