Right now we have 4KC in a 10x10 yard. We're planning on expanding that to approximately 25x25. In the end we'll have 10 ducks total in the yard (goal is 2 drakes and 8 hens). We also have 4 chickens (3hens and a bantam Cochin roo). If seperate housing is provided would that be adequate space for the chickens and ducks to share or are we best just keeping them seperate?
