Beautiful! Congrats on the rare find! It looks like the buff is a gander and the grey is a goose. To be sure, if you could post a video with them making noise, I will be able to confirm. If so, how lucky of you to have found a buff/grey pair. My greys have started laying as early as beginning February and as late as end of May. They will lay up to 30 eggs in their youth (if you take all but 1-2 eggs from nest). Otherwise, they tend to lay 15-20 eggs at best. It is extremely rare for them to successfully hatch babies, so plan on incubating if you want goslings. Assuming you have a buff gander with grey goose, you will have color-sexed babies. The boys will be grey (and carry buff gene) and the girls will be buff.
