Hello. I have 5 Pekin ducks, all about 3 weeks old, and I'm wondering what would be good for a duck coop. What are good dimensions for the yard and coop, do they need nesting boxes, roosts, etc. and other important things. I have read that they are able to share a yard with chickens, is this true? I'm really new to poultry, so I have no clue. Pictures would help Thanks in advance!
