Black Australorp pullets

[Ashley1215]

Do I have 2 black Australorp pullets? They look very different if they are the same breed. The one with a long tail is much louder, but hasn't acted "in charge". There's nothing that indicates the other one is getting pecked to cause her to lose her tail. They are probably around 5-6 weeks. Please tell me I don't have to tell my daughter that one is a roo! I love his/her baby purr!

Tails and personality mean nothing.
They both look like pullets thus far.
