I honestly don't remember when I hatched this chick (I know! In terrible! How you guys know your pullets are 16 wks old is beyond me!) but I think it is between 6 and 8 weeks. I am stumped on it's gender though. Please bear in mind that my phone makes the comb look very red. It is a Lightish pink, which still seems premature, but it is by no means red. Thank you!
