Hi, I have 3 pekin ducks that are 7 months old. Tonight I noticed that one of my females is lethargic, her feathers are very dirty, and her beak is pale. She is eating and drinking. I haven't had her separated long enought to see what is going on with the other end. All of the other ducks seem to be fine. If anyone has some helpful information I would really apreciate it. I can't seem to find anything on the internet that matches what is going on with her. Thank you!
