My mom's duck is losing a lot of feathers and hasn't laid in 2 weeks. The duck lives with chickens and was raised with a rooster. Our neighbors abandoned the rooster and duck and we took them in. We've had them for around a year and recently the duck has started to look horrible. We've tried separating her from the chickens but she gets lonely and depressed and quacks constantly. What should we do? There's no duck vets near us
