% of hatch after 7 day candling

[greathorse]

I am wondering if any of the frequent hatchers can use their experience to answer a fairly general question. I just candled 36 shipped eggs (7 days). All but 4 showed every sign of being a "good" egg, with veins and all. Assuming I have no issues with temp, turning humidity, what % of those eggs should I expect to hatch? In other words is the first candling the most crucial? I know lots of things can still go wrong but the incubator has been right on the money with temp so that should be OK.

Whatta ya think?

Sorry, I do not know the answer, but want to give this a bump!

Thanks for the bump. As many hatchers as there are I assumed I would get many quick responses. I have also discovered it takes new members a bit of time to get noticed. Kind of like moving into a new neighborhood. It just takes some time.

I cannot answer your question, my first batch are in the 'bator now. I used a broody hen for my first hatch LOL

Good luck! I hope you have a good hatch.

First candlings will tell you growth, lots of things can happen to cause quitters from 1st candlings to 2nd and 3rd. A 50% hatch rate is a really good one for shipped eggs. Anything can and will happen sometimes, I have had zero hatches to 90% on shipped eggs.

Temps, humidity, oxygen levels, turnings, opening the bator, climate and house temps all play a part. Lots of times you never know why one will quit.
