Gender guesses?

[Rhendera]

I have some chicks that I still don't have a clue about their genders.... Any input from more experienced chicken keepers? They are all 4 weeks old. Pictures are 1.5/3/4 wk stages.

Lavender Orpingtons:
1

2

3

Ameraucanas:
1 (I'm thinking, Hen)

2 (this one was getting a bit more pink/red on his/her comb this morning, and has some bumps where the other 2 are still completely flat... So maybe roo?)

3

I also have 4 Swedish Isbars but I can pretty reliably judge their genders already, so unless someone wants to see those pics I'll keep it at this for this post. Any input is appreciated. And yes these are Ameraucanas, NOT easter Eggers.

Amuarucana's #1 and #3 look like hens, but I can't tell with the rest

the last ameriucana looks like a pullet, but they’re still too young right now to tell for sure
