    I found this....read the part about turning eggs. It says stop turning at day 15 not 18?? [​IMG] Even the temp it says sounds a little off to me. Up to 103* for forced air? And up to 107* in still air? Am I reading this right??

    One of the things you'll learn, is that not everything is set in stone, and different ways work for different folks. Oh, and EVERY University, and Ag Extension office is going to have their own information, usually differentiated by a misplaced period, or a difference of half a degree.... LOL

    Interesting... it also says you should have a higher humidity?

    I wonder if that is especially true for desert climes?

    Well, what that little tear sheet was saying was that forced air should be at 99.5 to 99.75 F with lethal temps starting at 103. Not that you should incubate at 103, just that the little guys are no longer viable at that temp. Still air lethal temps start at 107. They are adjusting for the layers of heated air in a still air incubator.
    The paper did mention stopping turning at day 15. I wonder if anyone has ever tried this?

    btw, I did go back and look at the date on that paper- 2000. It's almost ten years old and I am wondering if it's actually older than that as not one of their resources has a website listed. Makes me crazy that folks don't date stuff that's posted on the internet. You could be reading something the early 1900's and not realize it if it's not dated. Sorry, just a small pet peeve:barnie [​IMG]

    It is confusing, it says to allow the heat up to 103, yet that is lethel in one of the types of incubators...what gives? Then the humidity.
    I assumed that you kept the humidity lower while developing and then up towards 75% on hatch day.

    Do you think that who ever wrote this may have had his bi-focals wrong side up?

    Everything seems ok on there to me. The stopping turning early is new but the rest is the same as other people are doing. The temperature discrepancy is because of thermal layering in the still air incubator that does not happen in a forced air incubator
