It helps to know which breeds, breeds vary in agressiveness or mellowness. What breeds do have? Are they all the same breed, or three different breed ages, or mixes , and also breeds that vary from small to large? Any banties involved, or small ones like Jaerhons, SSHamburgs, Spitz?

I just spent four days mixing eleven 4 day old Chanteclers with twenty five, two-and-a-half-week-old Brabanters/EE. The Chanteclers were up for it, kept jumping over the divider to be with the larger chicks, and pushing their way into the food and warm spotlight. The Brabanters had been flying over the divider to check out the Chanties food and were not pecking the tiny ones at all, just curious. The tiny Chanties peck the larger ones if they want to and the Brabanters just move away. Twenty Brabanters move and fly around at top speed, the Chanties just go with the flow or just watch and avoid being trampled somehow. They're chickens and know this stuff I guess. The two EE are the largest and one is starting to referee things, although she? should be a pullet and is colored like a pullet. Last night they were all snuggled together, although the Chanteclers stick together.
I don't know if this will continue to work when the Brabanters start chest-bumping and setting the pecking order. May have to separate them, but at least they'll know each other. This pecking order stuff starts I think at 3 and a half weeks? So I think your spread of a month/four weeks inbetween maybe too much. This was a lot of walks out to the coop and checking this last four days and nights!! and not knowing how it would go although it went much better than I expected. I kept telling myself the little ones were chickens, not babies, and seemed to really want to be with the other chicks. And bold by nature. Meeker or fearful chicks might have not worked.
