Thanks so much for your replyI candled and floated last night. No pips in the air cell
but when I float them 2 low float and move a tiny bit. This is why I think they are shrink wrapped. So my question at this point is can I assist if they haven't pipped the air sac?? And yes the one with yellow patch is one of the sinkers. But when I say sinker I mean they sink to the bottom with a little bit of buoyancy. Interestingly enough 2 nights ago these 2 sinkers moved! But not last night. Thank you!
That's tough. If they are shrink-wrapped before they've pipped internally, I would worry about whether their lungs have developed at all and if they'd be able to survive any assistance you give them. I suppose you could pip the shell through the air cell and see what the membranes look like and go from there. If they are shrink-wrapped, be cautious when you open the membranes. You don't want to break any blood vessels that are still attached to the membranes, and you probably only want to open the membranes enough to allow the duckling to breath and finish absorbing her yolk sac. Overall, it doesn't sound promising, I am sorry to say.
There are a few things that can lower the success of your hatch. Eggs that were shipped in the mail can be damaged in transit, and they won't hatch as well. Washing the eggs before they go into the incubator can cause them to dehydrate too quickly and dry out. If the eggs were not turned, then it would prevent the duckling from developing properly. Of course it is important to have the right temperature and humidity.
