Anyone ever have a problem with a duck that layed soft-shelled eggs? I have 3 young girls and I think it is a young cayuga that is just starting to lay. Over the last 2-3 weeks I've been finding a soft-shelled egg laying around the barn every 3-4 days. I have a rouen that's been laying for about 5 weeks but she has a nest in the hay bales and her eggs have been normal. The only reason that I think it could be the rouen is because the soft-shelled eggs are white and I've read that cayuga eggs have a blackish bloom.
