I was wondering if anyone could help me identify my ducks? They're about 4.5 weeks old now. When they were ducklings, they were all yellow. Two weeks ago, they started getting white feathers (I was sure they were Peking Ducks) - however their feathers are now coming in brown. Their breasts are a light brown, and their feathers near their tails and wings are white and brown. Their beaks are a light pink/brownish color. Here is a picture of them!!! I am starting to think they are Welsh Harlequins but am still not 100% sure. Any guidance would be greatly appreciated!
