What went wrong ??? EGGTOPSY - Suggestions please

[Nitin Kumar]

Hi,

I had three eggs remaining in my home made incubator. All three of the eggs died. I did eggtopsy and this is what I found. They haven't piped internally. None of them. They were wiggling a lot that means that they were trying to break the inner membrane but were not able to . I would like to know what are the possible reason? Could it be the humidity? as you can see below the membrane looks dryish. The head was still under the wing and the the chick was inside the inner membrane intact. What could have gone wrong?

What was the humidity? This has happened to me before and I've noticed that it doesn't happen as often with the correct humidity.

I would agree to low humidity. My best hatches have come from 70% or more in humidity. Seems as though lower than that they cannot break the air sack as though it to tuff to break

It was 55 until lockdown, then 65. I think my hygrometer is also not accurate. i might show more then actual.

Also the temp was always 100 or 101. Does it make any difference?

How can you tell it was cold or too much water. In teh above pic where I am holding the eggs you can clearly see its kinda dry. This is my first hatch and its a homemade incubator, I am assuming that it was low humidity and the membrane got dried up and chick wasn't able to break the air sac. And I remember the egg wiggling on day 18. The black one which was quiet big stopped on day 18 while the yellow one kept wiggling until day 21 then stopped. Whats your say now. And I just calibrated my hygrometer ( so stupid of me, could have done earlier) and humidity difference is about 4% - 5%. It shows 4% - 5% more then actual humidity. Will that be a factor?

If its to cold your hatch will be late. Chicks will be small and have defects. To hot they will hstch early usually be bigger and i have expereinced hatched chicks with some embryo. If chicks are having trouble getting into the air sack humidity to low. Like i said before get the humidity as high as possible when hatching. Check out porterturkeys.com/egghatchingtips.htm its the website i used when first started hatching. Turkeys are much harder to hatch than chicks. From there you can make adjustments to calibrate your system. My hatch rates for last year was 89% including quail turkey chicken and guinea chick. I hope i can do that again this year
