Chicken has habit to dig and throw the feed away during eating. If your feeding equipment is inappropriate (not well designed for feeding chickens), then you will find that many feeds will endup outside of the feeder.– This is a Waste !
This throw away process of feeds will happen everyday, every week, every month, as long as you breed them.
By using the correct equipment, you can save 3 gram of feed/bird/day. For population of 10.000 birds with assumption price of feed Rp5.000/day for 30 days, you can save = 0,003 kg x 10.000 birds x Rp5.000/kg x 30 day = Rp 4.5000.000/month.
