    I am incubating my first batch using a forced air vertical orientation incubator. I have been using broody hens but have switched to get a consistent schedule instead of hen time. I played with the incubator for a few weeks and discarded the provided control feedback display as it is completely incompetent.
    I do use the rotation mechanism as it has proven to be reliable.

    Now my question. I candled at day 7 and have 22 active eggs and 2 clears and 1 early quitter but the air sac is not where it is in the diagram you see to measure the weight loss. I am running low humidity (20-30%). What could be the issue? The eggs are looking good otherwise.

    What does the air cell look like? Is it just too big or too small for day 7 or completely in the wrong place like the side or small end of the egg? Or is it in the right place but misshapen?

    It is at the small end on the eggs. I put the eggs small end down in the collection cartons and shifted them twice per day. I only collected for five days.

    That being said, if they don’t work out it is a valuable lesson. My next incubator will NOT be this junk. Although I may use it for hatching as it does very well at holding temp and humidity.

    Take the egg with the air cell at the small end, and lay it on it's side in the incubator. Turn by hand at least 3 times a day. I've had several hatch that way, and the chicks were fine.

    I was considering just that! They are at day 8 so I thought I might have a chance to correct it. I will have to rig the turner as I work full time. But I don’t see it being a problem. Thanks

    Wow, it's so strange they all developed on the wrong end, I've only heard of so many having air cells in the small end if they were in the turner small end up. I hope your little ones still hatch out well for you, good luck! :fl

    So I just got home. I have recandled the eggs. 17 left out of 20 set.
    1- yolker
    2- quitters
    17- goers!
    Once I figured out that I was candling them incorrectly... I swear oldtimers is brutal

    Congratulations on having 17 looking good, it's great that the air cells are in the right place too! I think it's a pretty easy mistake to make, the light colored egg white at the pointy end does resemble an air cell. Good luck with your hatch, those babies/embryos look like they are growing beautifully! :)
