Today is day 21 for our little maran eggs. Last night, one of them shook and rolled quite a way in the incubator. It hasn't moved very much since. Before that, it was shaking quite a bit. Could the rolling have possibly killed it? Or is it ok for the eggs to roll? Is it ok to candle on hatch day? We are watching closely as the others shake, but nothing much else going on in there just yet. Any information would be so helpful! Thank you.
