hi, you are at the same stage as me, just been to see the incubator an one is moving, this means the chick is getting into the right position to break through the air sack if the incubator is somewhere quiet you my soon here the cherping sound and that sometimes starts the other chicks off, your on your way. hopfully tommorow when you get up or may be later in the early hours just make sure temp and humidity is fine,and the they should start pipping.
dont be tempted to keep opening the incubator as they are still very weak and need all that temp to help them on there way.
it seems so long turning eggs and now your not far from getting your chicks. GOOD LUCK AND KEEP CALM.I BET YOUR ALL EXCITED BUT NOT TO MUCH LONGER.
