1. I have two female mallards that are laying. both are breeding with their mates on a regular basis, so im assuming the eggs should be fertilized. The one originally popped the eggs out where ever she felt like. i put them all together in a "nest" in the corner of her stall and she eventually began laying them in the same spot and burying them. This is my first laying year so i really have no idea what the process is. She doesnt seem to sit on them very often. I see her on them occasionally, but the majority of the time she is off with her mate in the duck yard. the oldest egg is about 10 days old. will they incubate or is it a lost cause since shes not sitting on them? the other female has since started laying and she has been depositing her eggs in the same spot but she doesnt seem to sit on them as well. i considered a home made incubator... not sure if that will be easy or not. im at a loss!
