Should be fine. You do not need to turn technically after day 14. You can also wait until day 19 or when you see the first pip on the earlier eggs before upping the humidity.I dont like doing this but ive got myself in a pickle because ive got a staggered hatch rate!
Ive got 2 hatching on the 3rd of march and 3 hatching on the 5th, i have a manual incubator!
I'm going to have to open the bator to turn the eggs that aren't in lockdown while 2 will be in lockdown i dont want to shrink the lockdown chicks in the membrane but i also have to turn the other eggs! Any help would be appreciated Thankyou
