It doesn't really matter if she's a giant or an aussie. She has a home for life, either with me or my sister. My only concern is that I have very small bantams. A couple of my Nankin hens are only about 20 ounces. I don't want anyone hurt, even accidentally. Still, I have to admit that I'm curious as to what a Nankin/Jersey cross might look like. Black, I'm sure, but size and proportions could be, shall we say ... interesting?
She should be fine with your bantams if you integrate them NOW! They will grow up with the smaller birds and not think a thing about it. If you provide space so they can run off (bantams or chicks) they will be fine. I put my 2 week old chicks with the flock without incident. I have a mixed flock of 3 month old, 6 week old and 4 week old with the adult chickens and they get along fine! Think about it!
