Personally I think you did the right thing saving the egg, but maybe just maybe you could release him when he's older? Do ducks migrate down there? If they don't it may not be to hard to let him go when he's full grown.
Just a thought. If you did release him you could alway get some demes tic ducks to quell you duck fever down the road
And you could visit Qwackerjack at the park!
