Hello and welcome to BYC! Glad you joined.
Ducks can be prone to niacin deficiency and need water to swim and bathe in. They are cute slobs compared to chickens.
Study the duck forum and plan. They're sort of like very messy chickens that may need Niacin supplementation in their feed. Drakes and chicken hens can be a bad combination.
