Vicky,
I've been interested that so many of you are getting eggs now. My crew is noisy right now, and 4 of them are new this year, 2 that I hatched and 2 that I purchased, so suspect they are choosing mates. But no one is making nests and no one is actually mating.
I think your theory on soy is an interesting one. I got soy out of my diet about a year ago, when I learned how NOT good for you it was. And the geese, are on Organic SOY FREE feed. Soooo....??? Maybe your theory is correct? Who else has their geese on soy free out there? And what is their current breeding behavior? I find this topic very ineteresting.
