I'm going to have pekin/mallard mixes this spring!! I would hatch them earlier..... but it's so cold outside that the eggs crack because of expanding. So I can't until it gets warmer. I've never hatched ducks before... just chickens and guinea fowl. What temperature do they have to be at? What humidity? How long do I have to incubate them? Sorry for all the questions... I am so excited to be a 1st time momma duck! I guess it wont be until spring, though Oh well! It will be something to look forward to!
