I have a blue swedish female that just hatched 7 babies. 5 of them are dark grey with the yellow breast and black feet. They look like this:

The other two are a real light yellow with just a hint of grey. They have a mostly yellow beak and solid yellow feet. There is no defined bib on them, they are solid yellow. They look almost exactly like this:

But with a touch of light grey. I have been in the duck world for awhile now and have never seen any blue sedish like this. The father is either a blue swedish or rouen, but the babies do not have rouen eye stripes. Do you have any idea if they will turn a light grey, white, other color? I had a baby hatch in May and she turned into a really light grey color but her down was dark. If you have any pics of what you think they will look like please post them.
