where the air cell is I waited to day 7 when its a good size and I pull the shell of to make the air cell open but not cutting into the membrane. Then tape saran wrap over the open hole.
On day 16 I pull the wrap off and put it back on using Vaseline so when the chick starts to hatch it would just knock it off.
So it's just regular saran wrap? And do you put it against the membrane or pulled right across the top? And what do you do for turning?
