Oh wow! Goose eggs are worse than anything else...You have the normal incubation anxiety stretched out for a MONTH. Have you read Pete's thread on goose incubation?
Let us know how they do! Nothing cuter than baby goslings.
Embdens are big fat fussy-faces; I love them.
Excellent! What sort of eggs you got cooking there?
And yeah, I waited about 15 days before tossing my duds too. For chickens, I wait til day 10. A day 7 could fool you if you don't have a great candler. How bright is yours?
I wouldn't give up on those eggs just yet. Cooling isn't BAD for them per se, depending on how long they're cooled, and 10 late term goose eggs, if huddled together, can hold their own heat pretty well. By the same virtue, they will also resist changes in heat, being mostly aqueous critters...
