Good evening, I am new to mallards and actually new to ducks in general. We have 3 hen and 1 drake that are 6.5 months old. I didn't really know(or think) about eggs and happened upon 2 eggs in their pen exactly 3 weeks ago. I bought an incubator, auto turner, etc. I have a couple questions... 1. In order to hatch, do the eggs need to lay in the pen for any amount of time or can they go straight into the incubator? 2. My homemade candler showed a lot of yolk in every egg so either my candler wasn't good enough and I'll fix/re-check them or they're all not fertile. If the first group is all bad, is there anything type of rookie mistake I may have made that you guys have learned from? 3. If the eggs have been in the incubator and turn out to not be fertile, can those be eaten or are they just throwaways? Again, I'm completely new to this and honestly it wasn't in my plans, but I have thoroughly enjoyed my mallards and look forward to growing our herd. Thanks for your help!
