My daughter wants to hatch chickens at school. The teacher is excited about the prospect, and so we've set it up that the middle of the month, we'll set up the incubator in the classroom. But, the weekends :\ The eggs will be turned three times a day during the week, but that's not possible during the weekends. The teacher said she could get someone there to turn them in the morning and evening though. Would turning twice a day instead of three be too detrimental to the hatch?
