Different Aged Chicks - Okay to Mix?

[itgns]

The difference would be about two weeks at the most, I believe.
There would be more of the younger chicks than the older chicks. I only wanted one of the Buff Orpingtons if possible, would consider two (chicken math!).

When I was adding a couple new chicks I was told that usually under two weeks old is fine as after 2 weeks they've started to develop a sense of flock. Sounds like you might be ok. Mine wefe only a couple days apart. The 3 older ones were still only 5 days old though. They did fine. I don't think they even really noticed. I alsk introduced them at night. Which I also heard can help.
