Introducing new Chicks and what should i do?

[Swampy_9]

I first want to start to say that i dont have a big big flock. Unfortunately in August i was just left with my one Rooster and my one laying hen. So i only have an existing flock of Two. I Have however 7 six week old chicks right now. I know i have about 2 or 3 more weeks to get them into the flock, I did however have them in the run and my two others free roaming the yard, Given our A.C broke and it was getting so hot i let them get air. So my existing flock does know of them. They go see them and right now and for the past week or so don't care about them.
My rooster or hen sometimes goes and lays around the coop near the chicks but aside rarely they just go around the yard and do their own thing. right now since they are pretty big i have just taken them in my hand and shown them closer but they dont seem to care, just stare and then walk away i dont know if that is a good sign or not.
Four of my chicks are smaller however not by a lot but they can be seen as smaller obviously so im hoping for that growth spurt.

I guess my general question is, How should i go about introducing them? i know its not a big flock and they dont seem to care at all about them so should i be so worried? What is the general way i should go about this? If it goes well while they free roam should i coop them together? should i get a barrier between them for the first few weeks in the coop? I know pecking is to be expected but what should i look out for that is a bad sign?

The fact that there are more chicks than adults might be in your favor.
Most important is how much space do they all have?
Posting dimensions and pics of your coop and run would help here.

I like to integrate chicks very young, much easier(except for the space prep) than integrating older chicks.

Still, observe the.....
Integration Basics:
It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.

In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can really help. Lots of diversion and places to 'hide' instead of bare wide open run.

Good ideas for hiding places:
