Cool! Should be fairly easy to find an extra gander. You might try a wanted to buy on your local CL.
Finding a gander has been a little of a headache. I did finally locate a toulouse gander in ordway. I also picke up two females for my neighbor.
The woman i picked them up from was very nice. She has critters running around all over the place. Lots of geese turkey chickens and goats. She told me that i need more. Just let her know.
I should have some fertle goose hatching eggs soon. I will have full blooded toulouse and the other will be half tufted and toulouse. Goose eggs are a whole different hatching experience. I found that out last spring. If anyone wants to try. Just let me know.
