Hi! I have 2 ducks right now, a male blue swedish and a female black swedish. I wanted for females so my drake isn't mating my female so much so I ordered 2 females from Metzer Farms. I was wondering how much I should feed them daily?? Some people are saying 3 times a day while others are saying they can have food 24/7. Also how much for my adult ducks as well.. They are 7 months old and they have access to food all day except for when they sleep.. Thanks!
