That's a great question and I have heard sooooo many different stories about this.hi, im new to hatching anything ! i have some call ducks in the incubator but dont know if i should keep them close together or spread them out ?
but with my Experience it doesn't matter. Some say Don't let the eggs touch each other and some say it's OK.
But you have to think like a duck. Does a duck REALLY keep all her eggs separated when she's sitting?? NO, they do NOT. In fact, I have had them Pile them on top of each. I would not recommend putting the eggs on top of each other but I would say your SAFE in letting them touch each other. GOOD LUCK TO YOU keep us informed.
