Hahaha yea we got deceived last year when they hatched a female pilgrim looking gosling and we assumed it's a she. Turned out to be a gander with female pilgrim plumage.If that "female" came from the same parents, I wouldn't trust her sex either, considering the variety of colors & sexes you have already gotten in your mixed goslings.
If that gosling is a pure Pilgrim, but has the same father as the confusing ones, I would also check the sex rather than trusting the color to work right. The Pilgrim male is not producing the colors of goslings that a pure Pilgrim male should produce in crosses, so he might not produce the correct colors with a Pilgrim female either.
The pilgrim gosling I'm raising now isn't from my own geese but another breeder. They only have pilgrim so no curve balls.
It'll be nice to match up the 2 dark saddle backs together. At first glance, it'll trick people that it's 2 female pilgrims haha.
I'll show you the embden mother, pilgrim father and their gander hybrid.
Also can see my 2 ganders from same parents but mainly white.
