I recently got a beautiful pair of buff geese (boy and girl). The boy is currently 'dancing' for the female - flapping his wings and squawking. Very cute. They are currently in with the chickens. If the female starts laying (which I'm told happens in the fall), would her eggs be pure goose or would they be part chicken? LOL Is it possible for a roo to mate her? I really don't want to hatch unless they're pure goose!
