I had a broody duck hatch out a clutch minus one egg. After 3 days she gave up on it but I candled it and it was alive. I put it in an ice cream bucket on a baby towel with a heating pad around it. I'm spraying water in there four moisture. It's been inside for 3 full days and it had internally pipped about 48 hours ago (I could see the beak and hear peeping). No sign of external pip. Still lots of movement, but am worried babies conditions for hatching are less than optimal. Should I do anything to try to help? I could see yawning 24 hours ago so wasn't concerned yet, but am starting to wonder.... thought and advice please
