Hello! My muscovy female has become much lighter over the past months, she was a dark brown but now she’s almost white. I know her feathers are lighter from getting sun bleached. However, i posted a photo of her today comparing her to what she looked like a few months ago and one of my friends said her bill has gotten lighter too! She thought it might be some kind of deficiency. I don’t think it is but i wanted to come here for advice. She gets duck food daily and also gets worms and greens, and what else she finds in the yard. She’s so grumpy right now. She’s trying to go broody but she’s not serious about staying on the nest. She’s just so mean! lol. Here are some photos of what she looks like now and what she used to look like.
