Dirty looking bills...

[PetesMom]

What could it possibly be? I have tried wiping it off thinking they were just dirty as they didn't come from the most stellar conditions. They are pekins. We just got 2 ducks and a drake. The drake looks fine, but the females look like they have something all over their bills? I saw some like this at the local fair so didn't really think too much of it but it has me wondering..I can get pictures later if needed

Like dark greenish freckles?
That's normal and a sign of impending laying.

Looks sort of brownish...but I guess it explains it. I know atleast one is laying as I find an egg nearly every morning. I didn't know their bills changed color like that. They also seem to be going through molt..thank you for the info
