I have chicken and ducks mixs and the humidly avg 23 %
But when my chickens hatch it will be 75 %
on day 22 for my ducks should I put my humidity to 100% or is that a bad idea.
I do not know how to hatch duck eggs, but I personally would not have incubated them together. The humidity for chicken eggs for the first 18 days ranges from 55-60% and then bumped to 65-70% for the last three days.
Maybe, someone else that incubates them together will come along and help.
