I agree w
@Debbie292d - all of my incubators that have optional auto turners also give instructions for use without the turners.
Also. Remember that, even if the eggs were under momma, she would occasionally get up to eat, drink, etc.
Don’t be afraid to open the bator- just crack the lid, grab an egg to check it, replace it quickly and grab the next- rinse and repeat, and work quickly. The temp and humidity should bounce back once you are done. Just don’t pull the top off and leave it that way while you check them all
I don’t rotate my eggs in the turners, I just candle (w latex gloves on) :
- at setting (to check for small cracks that you can’t see without the light) -
- at 1 week to check for fertility/ development - and I don’t remove any at the 1 week check unless I find a crack that I’d missed before,
- at 2 weeks - to double check/ remove any infertile/ clear eggs, to verify progress on my turkey eggs (very hard to see anything at 1 week w a turkey egg)/ to verify development in any eggs that had good veining early on, but I wasn’t able to verify movement.
- at lockdown. I have a separate bator for lockdown, but, even if I didn’t, I’d still check them when I pulled the auto turner.
Also.
All with a pencil
- I write the date laid (small) on the top of all of my eggs when I pull them from the coops. It helps me keep track of what I’d like to set, what I want to sell to both incubation and “eating” clients, and what I might have gotten behind in in the shuffling, I eat or discard myself.
- every time I candle, I outline the size and locations of the air cell. I don’t weigh my eggs as they go through the incubation process... I monitor air cell size to adjust humidity if/ as needed
- I also mark the top of each egg when I candle them, with
. a + for movement,
. a

for development without movement when I was checking,
. a ? if something looks maybe not quite right, and
. an x for the ones that either didn’t start, or have stopped developing.
When I move them to lockdown, I add a + on the “top” side of the eggs- it makes it easier to tell who is wobbling, and who is close to zipping
....it also helps me re align the duck eggs if the turkeys hatch first and play roller derby with the other eggs in the bator before I can pull them lol
It’s helpful to also keep a notepad w your findings, dates candled, temp/ humidity at the different stages, any interruptions in either (power loss? Water tray ran dry?) and any other observations- if this is something you plan to do again.
Then be sure to add the final hatch results.
Some people like to number their eggs and keep track of them individually that way.... I tend to run 20-40 in a round sooo I just use tally marks...
Sorry for the info “dump” if you only plan to do this once

But it is helpful if you plan to do it often, to refine your process, and maybe even more so if you think you might give it a go every other year or so
