Canadians nesting

I have Bourbon Red Bronze and Narragansett turkeys. The three geese( not gooses) are all just Attwoods specials. One white and two African which I believe are actually from China? We've had them for years so the're old ladies. They make a terrible racket at any thing that moves. I cleaned out the pond several years ago during a drought and made two small islands hoping Canadians would nest. They have, and have been returning for three years!
