Issues with late embryo deaths

[Lacrystol]

I think the duckling has died, the air cell has gone a funny shape and there's some yellowing around the bottom. I sprayed it and got the humidity up but it may have already gone at that point and it didn't make it to internal pip

I think one of my muscovys is going broody so I'll leave it to her for now and try again soon with the khaki eggs. I'll mist them frequently next time and see if I can get some good results. Thanks for all the help

STICKY, sounds like a sticky baby,

What causes this? Was the humidity too high or low?

The broody muscovy has had her eggs taken from the house by crows! So will have to fix that problem first, it's never simple with ducks!

OMG, those NASTY CROWS, I've seen a crow take away a baby bunny that I tried to get them away from. they are horrible creatures.

High humidity
low temp
lack of ventilation
or
dirty bator.
