Month old (4.5 weeks) Bantam Mottled Cochin. Girl or boy?

[Barbara55]

Thanks again! These chicks are from mypetchicken, anyway, so I'll have to wait until the 10th week to make an official report. Still hoping for a girl

otherwise I'll only have two girls left.

I have 2 from my pet chicken as well! Mine are only 3 weeks old, so keeping a written record on feather development, etc. I read that if there is any pink/ red colour in the comb, it's a cockerel. But of course, it's too early to really tell for certain. I do have a silkie hen already, who always attacked me from a very early age.
It will be very interesting to know if it's a pullet or a cockerel!
