Cayuga Eggs

[Newchickenguy84]

I've had my ducks just over a year now. About 2 -3 months ago a few of the eggs either had no shells or very weak shells. I have given them oyster shell but no improvement. Was this due to them coming out of season? I have not gotten any eggs from them in the past 2 weeks so I'm guessing they are done until spring.

Sorry for the late response. I feed them and my chickens dumor 16% flock feed. Should I go higher for the ducks?
