Penny, but there is a lot of feathering, so I leaning more towards girl, but I guess if I had to pick one where there is a possibility, it would be that Penny...because it has a thicker comb.
I am just going off of what I have noticed over the past 4 weeks with my guy. He really started showing boy to me at around 2 1/2 - 3 weeks and this week, at week 4 (he will be 5 weeks Monday) I am sure he is a boy.
