My thoughts would be to put the three hens and the fifteen chicks all together in the biggest area you have. If at all possible, it would also be preferable to put the pullet/hen group in the area that already has the nest boxes in it so that they have a familiar place to lay their eggs. Make sure there are plenty of hiding places that the littles can run to for safety.
I think that as the little pullets outnumber the hens by a long shot they should (theoretically) be ok. There is a certain safety in numbers which goes in their favour!
Make sure you put out extra feeders and waterers as the older hens might try and prevent the young pullets from using their favourite ones.
The roosters can be separated into another bachelor pad pen of their own. I would try and make that in an area where they can't see the hens, thereby removing anything that may antagonise them and urge them to fight each other.
I would think that this separation should only be required for a fairly short period of time - maybe until the youngest pullets are 4 to 4 1/2 months old? They should be able to handle themselves by then, and you can attempt integration of the whole group.
