I don't wash the eggs before setting them but I do scrap of any big gobs!
I incubate and hatch in the same unit unless I have different hatches simultaneously, like right now. I moved 5 eggs out of the 40 egg incubator into the mini advance at lockdown. 2 dozen still in the larger unit.
Of the 5 in lockdown, two have hatched and I have put them into a brooder because they were jumping around and moving the other eggs.
One of the 3 remaining eggs has an external pip, and I am waiting for the others.
Brand new at this hatching stuff, this is the second batch!
