Two Polish chicks - age and gender unknown

[Ponypoor]

These two kiddos were bought at a poultry sale (I felt sorry for them), the seller didn’t know their age, I guessed they were about 7 or 8 weeks when I brought them home.

That was a few weeks ago, I would say they are around 10 or 11 weeks old now.

This was when I first brought them home:

Petra left, Leah right

This was about 10 days later:

Leah

Petra (I think )

Leah is in the back and Petra in front

Last weekend, I have trimmer their topknots so they can see, what fun for them now they fly up in the tree:

Leah

Petra

Leah to the left, Petra right

And this is today’s video:
Leah has the lighter tail
Petra has the darker tail

Let the guessing begin!

I lean pullet on both - crest shape prior to trimming looks feminine to me.

I was leaning that way also. But now not so sure. It’s hard not knowing their true age.

Might prove us wrong in both pullets, Look at the tails.
