Introducing new chicks

[dubenjs1]

A quick question, i have a flock of 6 chicks 11 to 12 weeks old in my coop, i have a second flock of 6 chicks 4 to 5 weeks old still in the brooder when and how is the best way to combine them. Thanks in advance for your help.

Id do it when they are big enough to take being harrassed cause that big enough of a gap in age the younger ones probably gonna get picked on. when you do combine just keep a eye on them. the larger the space you havethe less likely you will have too many issues. They gonna establish the pecking order anyhow but if they have enough space they can run away from a bully.
