Incubation!

[usmanshahzada]

Storage for longer than 10 days can result in slightly lower hatch rates, but unless they were stored in temperatures below 0* you still should have had some hatch.


Was it fertile? Could you tell?

I previously bought eggs from the same guy and were hatch naturally (broody hen) and the result was 13/16

But when placed in incubator result 0/24

It was written on the manual that came with the incubator that humidity should be between 65 to 85
While the guy from whom i bought this incubator said that it should be between 50 to 60

A common error, and one likely left over from when a wet bulb thermometer was the common way to measure humidity. 50% can work in some incubators and situations; I've run it myself, but I have yet to hear of a constant 65% RH working for anyone. I've seen many hatches wrecked by it.

Don't trust the manuals, go by air cells or weight.

Definitely sounds like an incubator issue, then, if you're sure they're fertile, but improper humidity would not have caused them to quit early on.

I would calibrate your thermometers. You aren't using the built in one, right? Forced air incubator?

Incubator or high humidity?

Incubator or high humidity?

Not sure I understand the question? If you meant the place where I said "incubator issue", I meant that as just not an issue with the eggs.

Whats the difference between Incubation period and brood period.. Check this image

According to this image too humidity is 55-70 during incubation period and 65-85 during brood period

You said it sounds like incubator issue so thats why i am asking
Incubator is working not fine or its just the high humidity that caused this problem

An issue with incubator settings or use, I meant. Apologies for the misunderstanding.

We really need more information to help. I'd appreciate if you could answer all of these questions:

How many thermometers are you using?
Have you calibrated them? I can give instructions if you haven't.
Did you candle the eggs, and if so, do you have images or a general idea of air cell size?
When did you terminate incubation? After the full 21 days had passed?
How many eggs total did you break open? Just the one with no development?

I am unsure what they mean by brood period. Lockdown, perhaps?

Yes, it's a quite common standpoint. You may choose to believe it if you wish, and if you get chicks, great—just sharing what's worked for me and many others on here that have hatched for years and had hundreds of chicks. For my own eggs, anything over about 35% will result in miniscule air cells and a poor hatch. @Farmer Connie had issues with this before, I think. Whatever you do with humidity, you need to adjust by the air cell—that much everyone agrees on.

My neighbour hatched by those parameters and didn't candle to adjust. Guess what? She gets terrible hatch rates, even worse than my average shipped egg hatch rate. So, it has to be adjusted for the individual situation.

A good article by @WVduckchick on the subject. In your case, IF you had little to no development in all eggs, I doubt humidity was the issue but it still needs to be corrected and monitored during your next hatch.

Thanks a lot for your replies! Will go through this link and try my luck again!
Thanks again!
