Yes, I realize that now. But we didn't know much about ducks then. Basically, someone gave us an Easter duckling since we had 40 acres and a pond, and it grew from that. Cracked corn was all that was offered as duck feed at the local tsc, and we tried building them a floating shelter, but they didn' t use it. From the duck books I've read since then though, it seems that most ducks prefer to sleep outside, and shelters are more for protection from predators and extremely harsh weather than anything else. I know that corn alone isn't healthy, but supplemented as it was with their free range diet of bugs, frogs, garden veggies, and stolen dog food, I don't think they were ever unhealthy. I still wish we hadn't had to leave them though.
