Hi all! Ive been using this site for advice during my first hatching experience, so i thought i’d turn to y’all for advice!! I rescued 13 Mallard eggs after Mama was killed by something. So far, 11/13 have hatched and are thriving. We lost one. We have one left. He pipped all the way thru about 46 hrs ago. He’s peeping and pushing but not unzipping. I hesitate to assist but also really dont wanna lose him/her. Any help is appreciated.
