Multiple batches in bator- Didnt turn eggs for first 2 days

[DAVE07]

Hey all.. me again.

I have another question. I am/ was running mulitple batches of eggs in my bator and ignorantly put in fresh eggs 5 days before a hatch was due. I turned them for the first two days however on days 3-6 only turned them once a day and had humidity at around 75% as I didnt want to disrupt the ones that were about to hatch.

The hatch went well and after the chicks were taken out and from day 7 onwards humidity went back down to 50% and turning eggs 4-5 tims a day.

I am now on day 9 and i candled a few eggs last night. I can see some of them forming well but not all (some only have veins but I couldnt see an embryo). What I would like to know is did I do a substantial amount of harm by having those eggs with a high humidity for 3 days and only turning them once a day?

Keen to hear anyone elses experiences/ advice if they have had similar circumstances.

Just my personal experience, but I had eggs at all different stages in my incubator.
I too would up the humidity but only to 65-70% when I had eggs/egg in the last 3 days.
I opened the incubator quickly to remove chicks and my hatch went well. Out of 12 eggs, I only
had 2 that didn't continue to form and I cant say that was from anything to do with humidity or
opening the incubator. I did have 1 assisted hatch because the baby was shrink wrapped, however
the other egg that hatched the same time was fine. I would wait a bit longer and candle again.
Good luck

I do staggered hatches but I have and incubator and hatchers. When it's time to go into lockdown I take the tray out of the incubator and put the eggs into one of the hatchers. I used to try to do staggered hatches in one incubator but I found to do it this way and to have one incubator and different hatchers I don't have to worry about the humidity. I have hand turned but now I have turners. I don't think it will hurt to not turn the eggs for the first couple of days. When I clean out my incubator and start over with a new batch of eggs I sometimes leave the turner off for the first day especially with shipped eggs to let the eggs settle while warming. Good luck and have fun...
