Need feedback please- housing different ages

Can I put 6 week and 3 month olds together without problems of them picking at each other? I've got the six week old chicks already, and picking up the 3 month old today. Hope I can coop together.

They are in the same coop, but are separated for now. The 3 month olds are about twice the size and i'm afraid they will pick on the small ones. Should I keep them separate until my young ones get bigger? I know the 6week olds will being playing catch up for a while compared to the 3 month olds. But I figured it would be easier to add to the flock now rather than later. Thanks in advance.
