I am thinking of getting a few Ancona Ducks from Holderread's in Corvallis, OR. I was wondering if anyone has had any experiance with these type of ducks? Also I am a duck newbie.. How hard are they to keep? Do they need a pond? I know they should have one. But is it required? Will they sit easily? Also I was thinking about getting young adults instead of chicks. What experiences have you had with Holderread's adults? Pics would be great. I was thinking about getting a Chocolate Drake and different colored hens (Lavender, Blue and Silver I think). Is 4 enough or to many? Thanks!
