Hello I've had my first three ducks for about 6 months a male runner, and a male Swedish blue, and my female welsh harlequin. And a couple months after I got them I got more ducklings, 6 more, 2 cayuga, 2 Rouen, and 2 more runners and they turned out to be a boy and girl of each kind. But that's my little duck family for ya. Anyways I finally started getting eggs and I'm sure it's harlequin my oldest. She laid her first egg on October 2nd and this morning laid her 4th one. It is much bigger than the first three and has 2 yokes. I want to try and hatch all the eggs i read up a good amount of info but advice is nice. I know it is low success of hatching a double yoker but I will try my darnedest I love my ducks and there little babies to be. I had my uncle help me make an incubator for them I've read to let them sit until you have more eggs before putting them in the incubator. How many more do I wait for?
