Adding younger chicks?

Fabulous!

As far as the chick integration - really its just a crap shoot and depends on your chicks. They may become best buds, or the bigger ones may be territorial. Give it a shot, and see how it goes, just keep a close watch in the beginning, and expect possible injuries/losses. Worst case, you section off an area just for the little ones, until they get big enough to integrate themselves...

Every so often a brooder idea comes along that's so different and just, well, wow!! When they're done with it, take it outside, shake it out, turn it inside out and wash it down. Wow!

I've done a 3-week spread. It worked fine for me. The little ones will get stepped on here and there but the older ones aren't likely to be territorial yet at 3 weeks. I'd agree that you should watch and be prepared to intervene if you see something alarming but ample room and a range of temperature might be enough to save you from having to integrate after the hormones start.
