Can it be done if I set the duck eggs two days later so I'm looking at around day 30 for both hatching from goose eggs going in? I'm not worried about brooding them together, that won't be too much of an issue, I am hatching them for someone else. I had a nightmare with goose eggs last year, but am going to give it another go now. So 99.5'F and 45% or so humidity until day 26 then up to 65% for the last, with a dip test on day 26 in hot water. Sound OK?
