I have three baby ducks. One male and one female for sure, not sure about the other one yet. How does this work? How long do I have to grab the eggs before they are no longer edible? Is it true once refrigerated the cycle stops? I do not want to crack one open and there is any sign of a baby in there. I'm truly scared if this happening. I do not want baby ducks, just the eggs to eat. Will they give me problems when I take the eggs?
