I let you in on a secret Ive used for years with sucess with small numbers of helped hatches.
If your having a hard time keeping humidity up you can create a second incubator atmosphere inside the incubator using sandwich baggies.
Place a few small holes in bag for ventilation and put warm wet cotton balls inside with open egg.
Keeps baby from drying out and opening the main incubator has no effect on drying them out while you help out clutchmates.
Used this for years doing parrots.
