New birds, whatever the type, will always experience some pecking from the established flock. You just have to make sure it isn't excessive. I have a very diverse flock of standard sized birds, silkie, banties, Polish, Americaunas, SLW, RIR--you name it. They all get along fine, and any banties that are older than young standard sized pullets will always be over the newer, younger birds in the pecking order. Most banties can hold their own, they are all attitude. :)

If you read my chicken info page, I've got me 'Meet & Greet' technique outlined there on how I introduce new birds to the flock. Works for me. :)

If you also read the page called 'Meet My Flock' I've listed the birds in their pecking order, top to bottom. You'll see that some of the tiniest banties are over some much larger birds. :) Really interesting how it works!
