What happens if you don’t turn the eggs in a incubator?

If not turned for long periods the yolk will eventually touch the inner shell membranes. When the embryo touches the shell membranes, it will stick to the shell and die. Regularly turning the egg will prevent this, and ensure healthy embryo development. … Turning also moves metabolic wastes way from the embryo.

Do eggs get heavier before they hatch?

the time period is from when the egg is completely formed to when it hatches. Chickens are animals, which means they need oxygen to live. The egg shell is gas permeable to allow for respiration to occur. … Carbon dioxide is heavier than oxygen, so it stands to reason that the weight would go down.
