Duck egg

[homestead 101]

i am currently incubating 5 duck eggs, one has what looks like a grey air sac, like the outside is turning grey just where the air sac is, the rest of the egg is white. Lots of movement , day 25. Has anyone had success with this type of discolouration before.

If the off colored one is still moving I don't see why you would have problems with it.

Hello..That sometimes happens when the Duckling is getting into position to begin hatching. It's like a bruise from the membrane. Nothing to worry about..Good luck..

Could also be a little leakage from the main sac, if it has internally pipped. Got a pic?
