Aylesbury duck query

[Flutterbudget]

Hi all!
I have 4 Aylesbury ducks just over 5 weeks old and 3 have an apricot/orange coloured beak whilst one has a practically pale pink beak. Is this normal? Can anyone tell me anything of it?

The aylesbury standard calls for a pink bill. Your yellow-billed ducks must not be pure bred. Personally, I prefer yellow and green-billed ducks because they have more capacity to store carotenes in their bill and skin, meaning that they are more resistant to vitamin A deficiency.
