I'm so sorry
How awful. There are a few possible causes for embryo deaths, I can only guess from here, but in a nutshell it's incorrect temperature, humidity, and turning of the eggs while incubating, lack of or inadequate ventilation in the incubator or a bacterial infection (if eggs were contaminated by dirty incubator or hands when turning), possible breeder disease (where did you get the eggs from?), it may even be hereditary... Can you tell me a bit more about the eggs and the incubation. What was your temp and humidity during incubation? How and how often did you turn them? Where did you get the eggs? How were they handled before and during incubation? How old were they? Etc..
- Where did the eggs came from:
I have 4 hens and a rooster at my place, eggs came from them, a mix from all the hens
- How Old were the eggs?
About 2 weeks, I gathered them over a period of 2 weeks
- Before Incubation
I kept the eggs at room temperature which is around 26-30 C
- During Incubation
I candled them on day 5, then on day 17, there are kids around in my house so they opened the bator a few times to peek in, but temperatures here are 33+ C there days and even if the bator is left open the temperature doesn't really drop quickly.
- Temperature
All through the incubation temp was 99 F
Humidity
I had no measure of it, but humidity normally is high in this part of the world these days, never below 50%
I had the water tray on the bottom of the eggs filled with water
Ventilation:
The bator is home made and has no fan, but I had openings on the sides for air to pass
Turning:
Twice a Day, at 10AM and 10PM
Towards the End:
After I candled them on day 17 I knew that humidity should go up now, so I put a damp towel under the eggs, and used to spray water to keep it moist for the next 2-3 days.
One of the chicks that is now dead, was clearly moving on day 17 when I candled it.
Does this info help, what can I do to save the other six on day 19, I am not even sure if they are not already dead
