I have 3 call duck eggs on their 23rd day in he incubation process. Most of the shell is full, but the air cells arent too far down yet. Just looking for any information as to when i should stop rotating the eggs for hatching? Ive lost a few fully developed ducklings and im really hoping i dont loose these babies. Also i have 2 others that still will need to be rotated, but i know the 3 will need to be in lock down what should i do?
