Baby Pekins nearly 4 weeks old- sex?

Hi everyone, I’m new here!

Can I get some boy/ girl guesses on my chicks please?

These are my ebaybies and I believe I got 2 frizzle lavenders and 2 lemon cuckoo!
I’ll upload 2 pics of each. Thank you.

I think it's too early to say yet.

The first picture looks like a cockerel.
Post some updated pictures of the birds free standing in 2 weeks.

It's a little early, but the first does raise suspicion. Beautiful Pekins!
