So my duck eggs are going on lockdown tomorrow (day 25) and some of my air cells are huge! I had a few that had very small air cells so I lowered the humidity for a few days. This caused the other eggs air cells to expand a lot! On some the dip is almost half way down the egg! What do I do? Lockdown is tom! Will the air sac continue to grow during the next few days??? Help! First time hatching ducks!!! So nervous!
