Okay updated the picture. Hard to see, was taken a few days ago, but its there.
And this picture... There are two goslings in the front obviously, but beside them on the right is one with an orangish bill.While the one above is like greyish.. kinda weird. Its been like that ever since he was born.
My Pekins all had bills exactly the same color. I do occasionally see hatchery quality Pekins with white bills. It looks to me like that's what you've got. Color of bill won't tell you the sex with Pekin.
Two of my six have the more flesh colored bill.
And makes it easier to tell who's who!! LOL
And it's no indication of sex. You'll be able to tell that in the quack and of course once drake feathers develop.
