Can I put these chicks together like this?

I have 7 silkies and 3 Japanese bantams that are about 2 weeks old. They seem to be lively, growing fast & healthy. I have a batch of 5 Easter eggers & 5 New Hampshire Reds coming on August 5th...
Do you think the little head start the bantams got will be enough to mix them with the new batch of standard chicks? They'll probably only be about 3 weeks apart.

You might want to give it a week or two on the new chicks so they can get thier strength so the older chicks don't run over them. After that I don't think it will be a problem. I've mixed chicks like that in the past.
