So, after a 0% hatch rate for ducks in my first attempt (5 eggs), and knowing I couldn't better 84% for my second attempt with chicks (2 of 12 were infertile) I wake up this AM to find one chick cheeping and has successfully pipped the outer shell and made a significant hole for itself, growing slowly. Assuming nothing catastrophic now, that means I got at least 8% right. Most of the other eggs are two dark brown to have successfully candled (any flashlight recommends??) but there were a couple I'd swear I saw movement in. And a few that didn't seem to be filled enough with "dark" -pretty obvious air sack (1/5th egg?), large dark spot (1/2 egg), and something in between for the rest, about which I am very nervous. Today is day 0, but the eggs were collected over three days, so I guess I'll keep this thing running till mid- next week, and move hatchlings to their brooder as they dry out and pair up???
Its the back egg - the one in foreground is marked with pencil 2-10A (Day 2, 10AM) and a suspected dud. I can't read the marks on the hatching egg to determine where it falls in the timeline. Two of the others I'm hopeful of are 3-7A (Day 3, 7AM).
In the future, should I use grease pencil instead of actual pencil? I assume I shouldn't use magic marker...
