Incubating problem unabsorbed yolks
vanalpaca:
I broke open the eggs from the second hatch, had rockers on day 18 and 19 and one on 20, but no hatches on these last 8 eggs.
Yolks were unabsorbed.???
I checked my thermometers in ice bath and took the ones that read 32 degrees and am now going by those.
If yolks aren\'t absorbed is it temp low or humidity high or either, anyone know?
Thanks.
Beth C:
It could be embryo burnout. I was having a big problem with quiters after day 18, rechecked my thermometers, adjusted humidity, etc. and nothing seemed to help, then Michael suggested upping the protein in my breeder ration and it worked like a charm.
Jean:
High humidity and too high temperature can cause premature hatching resulting in unabsorbed yolks.
My temperature in the hatcher is 1 degree lower than the incubator.
vanalpaca:
Not hatching.
On day 23, opened up after checking for heartbeat.
Chicks dead in shell with yolk not absorbed.
Ran low humidity first 18 days.
Then upped humidity for hatching.
I will keep trying. I looked at the troubleshooting pages online and nothing addresses unabsorbed yolks and NOT hatching.

Hi Bonnie!
Happy Birthday...yesterday.
How many different breeding pens do you have? I mean, are you experiencing this problem in multiple pens? I\'m just wondering if it could possibly be pinned down to a specific rooster or hen that may not be throwing strong enough chicks to make it full term. If you had more than one breeding pen, you may be able to tell if one pen hatches better than the other.
Also, I noticed what Beth said (that Michael had suggested) about upping the protein in their diet. Sounds like good advice. Let us know if you get it figured out.
