mixed bantams or all same breed?

I just wondered whether its best to get a mixture of bantam breeds, or whether its easier to stick to one breed.
I was thinking one orpy banty, one pekin and one wyandotte banty...would this work as a combo?

Thanks

I have a right old mixture of banty's. Silkie's, wynadotte, pekin, RIR and some silkie x cream legbars, they all get on fine together.

Thanks. Choice for bantams as opposed to others is a space issue (seems far fairer to get 3 banties than 2 others), and then I have gone for those breeds as from what I have read/been told they are pretty hardy and should be easy to manage (perhaps slightly with the exception of the pekins feathery feet). Our aim is that they will be pets so eggs are a bonus...so I'm thinking broodiness isn't a problem as such, although I don't know if it causes problems if you don't "break" their broodiness other than of course you won't be getting eggs.

Wasn't sure if there were any issues on certain breeds not being compatible with others..

Thanks ANHBUC, I had no idea it could be so detrimental to their health.  I am learning so much and I don't even have chickens yet.
