Please help! Is it normal for the side of my duck’s tongue to be white-ish? If not, does anyone know the cause?

[Drowsy_808]

She’s one years old and she’s a Pekin duck. The side of her tongue has been white for awhile now and we still have no idea why. She eats and drinks fine. She sleeps well and she can be pretty active too. However, the side of her tongue is white and sometimes white slimy stuff makes it’s way to her mouth. Does anyone know the cause for this??

Can you post a picture of her ?
