They aren’t grey geese. Pink beaks indicate that they’ll be white, buff, or some other dilute form.
This doesn’t necessarily mean that they are embdens, they may be some other breed or crosses.
My french toulouse all had black beaks as babies, true grey comes out with black beaks but that doesn’t mean that they’re toulouse or that if they are pink that they aren’t toulouse either. There are buff and white toulouse but they tend to be uncommon and very pricy.
What I think you have here is that one of the parents were grey and marketed as “toulouse” which is the lost and found bin for every grey bird with unknown pedigree, because grey is the base color every breed came from, but the goslings inherited its looks from the other parent. They could be pilgrim, they could be smooth sebbies, you don’t really always know looking at a grey bird.
Either that or they just sold you whatever and lied.
Unless you’re shelling out money for a dewlap or exhibition Toulouse it’s hard to tell if it’s toulouse or part bred just looking at a grey bird. French Toulouse aren’t much different than production Toulouse, they aren’t show quality, they’re more of a novelty breed metzer got from Toulouse France and were never meant to be anything more, but people have been since marketing the descendants of birds they got from metzer or in many cases from wherever as “French Toulouse” and charging a lot for them like they’re Marie Antoinette’s jewels, just because “french” sounds fancier. I absolutely love mine but point is they are just a production Toulouse and their genetic phenotype is all over the place.
