A duck farm — a very very small farm of about 1000 ducks, in Asia yields about a modest €150/daily in profits, multiply that by about 25 days that would equate to about €3,750. which really is not much, but that's on a very small scale. Consider labour is très affordable there, a good acreage with healthy infra would return well. Interested in Agrotech in Asia? Drop me a note.
