So, I know candling is used to check on the growth of eggs during incubation. What I would like to know is the proper way to candle that causes the least amount of distress to the eggs. How early after being laid should you start candling the eggs? How frequently should you do it? Is it harmful to turn the eggs in hand while candling them? Thanks for any help or advice, I was surprised with a clutch of eggs I was neither expecting or prepared for, so I'm having to learn as I go.
