When can I introduce younger chicks to a 10 week old chick?

[rosemarythyme]

The brooder that the older chick is in is about 2.5ft x 2.5ft x 2ft. Her outdoor coop and run is not fully built yet, but it should be finished soon and then she can go in it (unless the smaller chicks need to get adjusted to her first because the outdoor coop is pretty cold with no electricity supply)

You definitely do NOT have space right now to put the younger birds with the older one. The babies have absolutely nowhere to escape to when chased.

Get the coop finished up at least and the older bird can go out. The younger ones will need to wait until they've been weaned from heat and acclimated to outdoor temps, and at that point I would begin see but no touch for up to 1-2 weeks before letting them have contact.

Normally I'm one to say put them together, but your situation is different. Try to put them in see no touch as much as you can. Once your coop is built and the younger ones don't need a heat source, put them together with plenty of places for the younger ones to hide from the older one.

Alright noted, they haven’t been together since yesterday so it’s ok for now.
