Last night one of my ducklings pipped and was peeping away, this morning - nothing. no rocking, no peeping...nothing. Something felt off so I candled it (i know, bad) and I can see his beak in the air cell..but there's no movement, nothing when i tap the egg. I'm thinking it's dead, should I open it and see or should i give it more time? Also, one of my other eggs has a giant aircell. It goes nearly all the way down to the other end of the egg...is this normal? I incubated with a hovabator 1602n at 101F and about 60% humidity.
