Will they get along?

[raisinginalaska]

I have four 6 week olds and three 1 week old chicks. Since its been in the 70s here during most part of the day, I've been letting the littlest run around the yard with the older four. It seems like the four stay together and the three stay close together but don't intermingle very much. Is this normal since they aren't used to each other? It sounds strange, but I want to make sure I won't have any issues when the little ones transfer to the coop.
thanks!

Mine don't have quite the age difference that yours have, but we introduced a week old chick and one that was a few days old in with 4 and 5 week olds, and they all got along fine. In fact the littlest one walked up to my oldest and pecked at it, which luckily was met with indifference from the older chick. They'll get used to each other eventually.
