Hi! I'm new to hatching chicks. A chick pipped this morning, but in the middle of the egg away from the airsack. Also, the membrane is paper white. He's chirping like crazy and moving his beak in and out of the hole like he's trying to get out but can't move into another position. My question: when should I intervene in case he is malpositioned? Is it ok if the membrane is thick and white? He's my first one to hatch so I'm not sure how a "normal" hatch is supposed to go. Thanks.
