Solid colors are harder to tell but the comb is looking rather masculine on the blue one. Add in those hefty legs and I suspect you have all boys.
Man, that sucks. Looks to me like they are all roosters.

Thank you all. I was hoping the ameraucana was a hen with masculine features. Can a hen have 3 rows on her comb? Oh well, the breeder did say that she would take back any that are roosters. At least my broody hen got to raise some chicks.

My Pearl has a little cluster..seems like more than one row but its not a defined 3 like I've seen on some..I'll snap a pic tonight.
She's been laying for 2 weeks or so now. I know it's her because she was the one strolling into my laundry room to do her thing

My Barred Rock is my "top" hen, as far as pecking order goes, so she's a bit of a meanie.Every chicken is different. So far, I have found my barred rock hens to be not to welcoming of newcomers. They peck at the younger ones and they run away. Also, my brahma isn't nice either. I have found the sweetest and nicest two breeds that I have are EE's (my favorite) and salmon faverolles. Again, it all depends on what breed you get and the personality of each chicken.
She's the only one who would go WAY out of her way to chase any newbies.
I've only had her though, so I can't speak for the breed as a whole. I've heard some say that their BR is their friendliest bird.
My EEs are the most affectionate, with one of my Orps close behind.
Ah, mine came from Meyers. One was a yellow chipmunk, the other was a red 'munk.Both were from my local feed store in CT. Not sure where they got their chicks, actually.
I've never followed the EE threads as closely in the past because I didn't have my own, but it seems to me that somehow there are a lot more of the black/white varieties this year. Right, or am I imagining things? It's unfortunate because they are known as being a little tougher to sex, and I wanted nice warm colors! I picked two very different-looking chicks (yellow with messier chipmunk markings vs brown with very defined markings) and now as juveniles they're like twins. As long as they grow up to make eggs rather than mounting my delicate little bantams, I'll just be grateful.
By 10 weeks they looked almost identical. Then as one got closer to laying, she got more chocolate and cream rather than black and white, and she had some light Salmon lacing come in on her chest.
