Help! Do I have a Roo?

[OsideChicks]

Hi my name is Gabby.
This is my first time doing this so I am a newbee. I just got a couple of chicks 7 weeks ago and 2 more 5 weeks ago.
I got them because I thought it would be fun, and to keep my mother busy now that she has retired. By the way she is having a blast with them. Although I am afraid that one we named Chucha could be Chucho… if you know what I mean. Her comb is a lot bigger than the other girls. I have attached a picture maybe someone can help figure out if our lovely Chucha is actually a rooster. She/he is about 6 weeks old. Also I think she could be a Ameraucana or a Araucana, just from what I have seen on line, but I'm not sure I don't have very much experience with chickens yet. The last photo is my other chick Rosa Blanca that I got at the same time I got Chucha they are the same age.
Thanks in advanced.

Welcome! They both look like hens to me!

It looks female, except for the comb. If they gave you her correct age and she really is only 6weeks old in the pic, then I'd guess roo.

Thank you for the response! That makes me so happy

I'm leaning toward roo. Could be wrong tho, lol.

Oh no. I was afraid someone would think she is a roo?

Yes she is actually 6 weeks old. I took the pictures today.

Based on comb, color of feathers, size, etc.. At the age. First ones a cockerel, second is a pullet..

Thanks everyone. I think I am leaning towards a roo as well.

Can anyone tell me what breed he could be?
