Hi, heres ny two polish chicks. Biff and chip.

Biff (black feathers) is 14 weeks.
Chip (grey feather) is 12 weeks.

Im sure it should be obvious now, but i just cant seem to 100% indentify their sex.

I have a feeling Biff is a boy and Chip is a girl.

Please anyone have any certain answers?

Thankyou

I can't tell if Biff is a cockerel or pullet, but Chip definately looks like a pullet. Do you have another picture of Biff?
