3 week old chicks - Roosters? Breed ID?

[lilhomesteadinmi]

I got my chickens from Tractor Supply 3 weeks ago today. 4 out of 6 of them have developed combs, is this a sign that they're roosters?

Doodle was sold as an Australorp pullet.
Dumpling was in the assorted bantam bin and I've learned that he/she is a Sebright.

Patty and Shelly were sold in a "Silver Laced Wyandotte Pullet" bin. I was told they're really Buff Orpingtons. Patty is significantly darker, bigger and they have different comb shapes. When I searched her it the first thing that pops up is Orpington chicken but when I search Shelly the first thing that pops up is BROILER chicken?! Please help..

Not necessarily but it's to early to tell, once they are fully feathers post new pictures of the whole body of them.

Did u buy pullets or straight run? Straight run you have a bigger chance of getting cockerels in the mix

I edited my post. This is my first time posting on the forums and I accidentally posted before I was ready.

I don't see in waddle development either, that's a good indicator that they are more than likely pullets..

Once fully feather an a few more weeks it will be a little easier to see.

Full body shots will be better for determining breed. Still a bit earlier to tell genders. I'd repost pictures in 2-3 weeks.
