Try hard to not candle during the first 7 days. Your hatch rates will go up.I'm fighting a candling addiction. I'd make candling a part of my evening routine and make sure that I always have eggs in the 'bator!!!
But I need a second incubator so I can set eggs more often then I can candle more often then I can have chicks more often, but then I'll have to build coops and pens more often. Hmmm Oh, well.
The spinning Tea Pot makes me want to go to Disneyland!
