Do bantam duck eggs hatch sooner than standards? I am so excited. I didn't have success with the call eggs that I had, but the australian spotted duck eggs, 5 out of 10 are growing beautifully. If I go by 28 days, they are due on the 29th. I'm excited as I've never hatched out duck eggs for myself before (but did really well hatching runner ducks for my aunt last year). Trying to figure out how to keep the humidity up, too since it will be in a Sportsman in a bottom hatching tray. Should I put a wet paper towel or towel over the top to keep the humidity up down there?
