Integrating chicks 1 month apart?

[Michelle_Mel]

Hi all, I hatched 3 chicks and one month later hatched 6 more. They are currently 7 weeks and 3 weeks old. Approximately how long should I wait before putting them together?

Can they see and hear each other now? How much space do you have for all of them? Integration can start when the youngest batch is 4 weeks old if they've already been exposed to each other. The toughest time during integration is roost time even if you have the recommended minimum 1 linear foot of roost space per bird. So be prepared to have to go out after dark and shuffle birds around to get them where you want them.
Make sure that there are multiple feed stations and lots of places to hide and perch as well as organic substrate to scratch through.

I started to integrate at 3 weeks with see-no-touch. The older chicks can definitely be a bit rough, and some will care very much about pecking order and putting the littles in their place. You do not want to risk injury when they're this little.

DobieLover's advice is spot on. If you offer some details on your setup (Are they free ranging, or are they penned? How much square footage? Is everyone large fowl or are there bantams?), then someone can offer you more personalized advice on how to proceed.

They are currently in separate brooder areas but can see each other separated by fence while outside. I have a new 8x12 coop that I am just finishing up for them. They should have plenty of space to move about. I also have a separate flock of 10 adult hens that will eventually be introduced once the 9 little ones are older. They have their own completely separate coop but will all free range together eventually. Silly me for incubating so close together but my first hatch only resulted with 3 chicks.

How soon will the coop be ready? Will it have a run ready when the coop is ready? Are the 10 hens in another coop/run?

@DobieLover and @thecatumbrella have good advice and questions.
