Help Please! Is my Ameraucana a bantam or dwarf?

[iferdybas]

My little one really is quite active! She eats and drinks along with tall the others, but likes to run underneath them and hang out between the bigger ones legs. She acts like a chick but is 7 weeks old. They are all still inside because of the weather, but we are planning on getting them into the coop this weekend. I worry that she will be too cold and that the others will roost on a bar too high for her to get to. She doesn't like being separated from the others either. She will cheep and cry until we put her back with the big ones. We had tried separating her with the smaller chicks that are only about 5 weeks old, but she wanted no part of it. She made a lot of noise until we put her back with the big ones.

Any suggestions???

Could you post a comparison picture of her and a chick if the same age?
