To much ventilation?
Benny, position is important when you open them
hatching position and the six recognized malpositions Images: click here
as is letting us see pencil marked air cell size
AND if any fluids are in the egg
And what the egg shell looks like ON THE INSIDE
EGGTOPSY REMINDERS FOR EVERYONE
For us to help see what may have gone wrong with the hatch/chick/embryo we would have had to see the aircell marked at least day 18, then before you open up the egg candle again and mark it with a different color. FOLLOW THE ASSIST ARTICLE just in case its alive, If the float test shows the chick is dead, Start by taking the top off the egg as in the assist article, take pics as you go. Take a pic of the membrane over the chick. make sure their is no movement of the chick, wet the membrane get another pic see if you see its beak, open membrane take another pic and see if chick is in the correct position to hatch. see aviagen link for positions and break outs. Head underwing or head down. there is alot that could have gone wrong that can be detected from all of these things. is the chick big and wet, is there green jelly in the egg? is their broken yolk in the egg? and so forth.
