325 ducklings survived the 19 degree celcius weather conditions. We administered some duck plegue vaccinations last week. They are 500-600 kilo now. per day they consume about 1-2 taka worth of feed. 365*300=109500 taka will be spent to feed the 300 birds in a year. they will start laying eggs at 5th month and continue for 7 months. Therefore 7*30=210. 210*300*3=189000. 210 days multiplied by 300 birds by 3 taka per egg will fetch 189000-100000= 100000 taka gross profit. Of course we will have to cut the management cost, losses by theft, natural causes, capital costs etc. But if we raise the number of birds. The yield will be higher.
