If you can quarantine properly, then do so. Several hundred feet apart, do the chores of one set of hens, change clothes and shoes and do the second flocks chores. That prevents nearly all transmission of diseases. If you have a valuable flock, a large flock, and the space, this is a very good thing to do.
If you don't, then you cannot quarantine. Many people on here, pretend to quarantine. Personally, if I know the place, or the poultier, I don't bother with a quarantine. I like having a flock, but only have about a dozen birds, and take the risk of losing the works. Which I admit, would suck, but I would start over, and so far I have added lots of birds with darn good luck.
I do not add birds from an auction or a swap, or birds that have been to a show or rescue birds. They have been exposed to a lot of birds, usually right next to a lot of birds, and they could have picked something up and bring it home to me.
Generally speaking, healthy birds look heatlthy, then they are healthy. Not always, there is a risk...... but then there is a lot of risk with this hobby, and sometimes birds die.
As to the etiquette, the op sounds like she is getting mature birds. I am hoping from all one place. IF so, just put everyone in together, shortly after dark. If the op truly has enough room, there will be very little problem. The new birds may not lay for a couple of days, or lay once and take a small break. Other than that, I have done this several times and had very good results.
