Please tell me I have mostly hens!

I got 7 assorted chicks from the feed store that are now about 7 weeks old. I got 7 in hopes of having at least 5 hens, since we don't want roosters, or at least no more than one. Now I'm so attached to all of them that I can't bear the thought of getting rid of any!

What do they look like? I hope I haven't posted too many photos!

1. This is Annie:




2. This funny-looking thing is Baby, and what is that on it's head? A topknot?:




3. Chancla, who loves to sit on my shoulder:




4. Dave:




5. Ethel - very sweet chicken:




6. Franky:




7. Gabby - Not much doubt about Gabby's gender, I think! Darn!:

 

Thanks for the feedback. I was pretty much of the same opinion. These were st. run chicks - mixes - or "just chickens" as the guy at the feedstore said. "Take all six, or none", he said. So I took all six, plus Baby, who is named Baby because it (he?) is a week younger. All except Baby and Gabby are very mellow and calm. Baby runs around like crazy, getting into trouble. Gabby has to be the first to do anything, and the rest follow. Baby and Gabby have been having some pretty serious confrontations - another reason to suspect both are roosters. Dave is calm and mellow. If he's a roo, he'll be a sweet one, I'm guessing. I hope Chancla is a pullet! She's my favorite!

Any ideas on what kind of mixes they might be? He mentioned Ameraucana and Wyandotte and, obviously RIR. But where'd the topknots come from?
