Hello- First time duck keepers here. We're going to raise 4 Welsh Harlequin ducks outdoors. I was planning to build a raised coop, not unlike the henhouse of "the Garden Coop" plan. Then considering having a 4' kiddie pool halfway under the house and halfway under the ramp in front of the house. That way it should still get plenty of light but part of it would be shaded. This would make very good use of the space I have available and the pool could be easily maintained from a gate in the back. Is this plan a bad idea for any reason? Also, I found reference that ducks do not need nesting boxes. Is this the case? Their house is empty except for bedding? Thanks for thoughts.
