Bantam Breed and Gender Help!

[SwampPrincessChick]

I got four Bantam chicks from Tractor Supply two days ago, and they are one week old in the pictures. All of them (except the brown chick) have a split in their wing which would indicate they are male, though I have read that Bantam chicks feather more slowly than Standard chicks. Also, none of them act like males. I know it is very early to be trying to tell their gender, but I know wing sexing is easy to tell from. I don't know the breeds of Chick #3 and Chick #4, so I don't know if they could be autosexing...

Note that I am NOT looking for the breed or color of Chick #1 and Chick #2. I am only looking for the breed of Chick #3 and Chick #4.

Chick #1 - Old English Game Bantam - Gender?

---

Chick #2 - Golden Sebright - Gender?

---

Chick #3 - Unknown - Breed and Gender?

---

Chick #4 - Unknown - Breed and Gender?

Thank you for your help!

They're still too young to tell

Way too young to be determining sex of.

PS. Wing sexing won't work with them.

The split means nothing it is simply where the primary feathers and secondary feathers meet.

That's a breed that I had thought to be a possibility for Chick #3! Happy to hear that I may have two Sebrights.

Wing sexing is only possible on the first day, on lines bred for it.

So, the split in the wing (not pin feathers) at one week old is false? Or only false in most breeds?

It's false in any line not bred for it and it has to be specifically bred for and only applies to day 1.

The split wing thing is completely false. Not sure where that came from.
The way wing sexing works is by breeding a male with the fast feathering genes to a female with slow feathering genes.
Feather growth rate is sex linked so you have to cross certain birds a certain way for it to work.
They're crosses not a line of a certain breed.
