I have all of them in the incubator right now, with three goose eggs, everyday I open the door and mist the duck and goose eggs. Someone said to take them out and let them cool for 10 minutes or so, but I never seem to have the time to do that, so they just get a spray everyday. I also read to keep the spray bottle in the incubator so it is the same temp as the eggs, but I haven't don't that either. I hatched a few goose eggs last year and that is all I did.
Of course they didn't get a spray when the lockdown was on and chicks were hatching. I really havn't done that many so not sure how it affects the other eggs.
