I have a female Rouen, a female Blue Swedish, & a male Blue Swedish Duck & I was wondering if I should leave the eggs & let the Rouen sit or put them in the incubator. One of the ducks started laying on 1/11/13. I put the three eggs I got since in the incubator because I didnt want the eggs to freeze. Should I wait to see if she'll sit or what do I do? -thanks!
