Thanks Karen!Hi,
I was discussing with another lister recently. And found this article to share during the discussion:

"Meeting embryonic requirements of broilers throughout incubation : a review"
This is a fabulous review of all the topics I have been studying these past months. I couldn't have said it any better myself. The title topic is a many faceted gem . Figuring out the proper proportions and how they go together will be such a boon to the broiler industry. And the layer industry too.
The most important parts of the article are the sections on :
Abstract
Incubation CO2 Concentration
New Insights Into the Incubation Process
Conclusions

It is a good article--and they stressed temperature as the most important factor. Adequate turning, temperature plus or minus .5F from 99.5 and humidity in the 25 to 50% range with fertile eggs will get a hatch rate over 80%. Other things like the CO2, cooling cycle and misting will eek out a couple of percentage points above what the top three things will do.
Most people that hatch on a small scale cannot keep the temps, humidity and turning up let alone work on injecting CO2. That would be for large scale hatcheries.
My advice is to work on the basics and get them optimized and then go for the last couple of percentages in hatch rates.
