6 week old chicks run question.

I have some 6 week old chicks that are fully feathered I am going to move them out to the coop with my big girls the coop is devided so they can only see each other. My question is Would it be ok to put them in the run with my silkies during the day? My big girls free range so no run attached to the big coop. The silkies run is plenty big for the number of birds I would have in it. The silkies and these younduns are well aqainted as they shared space on my back porch. They are in seperate ex large dog kennela on the back porch right now.
