Who wants to play a game???? Who ever can come the closes of guessing the day and time of when the experiment chick will hatch will get a shout out on here and on my next YouTube video!!!!!
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.
