ok, i'm not sure what's going on, and am hoping someone can offer help. i've had 3 baby ducks hatch and they aren't absorbing thier eggsac like they should be. i have the latest one wrapped in a wet blanket, one is still 1/2 way in the shell, and i had left him overnight that way hoping he would absorb the rest of it and finish hatching. their tummies are totally flat. could this be a genetic problem? and do i cull them, or let them try to finish it. i read on the forums about pushing it back in, but am petrified to try it. i did have 2 successfully hatch, and now these problems.
