Standard pullets, bantams, and meat all in one coop?

[justlearning]

We bought 4 pullets and 2 straight run from TSC as layers (now 5 weeks old). We think one is a roo. May 3 we will be getting 5 roaster pullets from 4H. I was thinking if we were to introduce additional layers now would be the time to get the additional chicks. Was just at TSC and they had some adorable bantams. Was good and didn't purchase until I knew if it was ok to raise standard pullets, meat birds, and bantams all together. Unfortunately the roo is going to have to go since we live 1 block outside city limits. We'll wait until we are sure. Our coop is 8 x8x8 (we converted my kids fort to the coop)
