How does a 12-year-old Australian boy make a fortune running a chicken farm every month?

An Australian boy has become a successful young businessman by selling eggs
According to a November 2 report by Australia's Daily Telegraph, a boy in Australia who is only 12 years old has become a successful young businessman by raising hens and selling eggs.
The 12-year-old boy is named Calvin Moran. After initially looking after dozens of hens for his mother Vanessa, Calvin came up with the idea of starting a small business called Calvin's Eggs, supplying eggs to the local church every Sunday.
Before long, Calvin realized that his hens were "sitting on" a potential gold mine. He began saving his daily pocket money of 5 Australian dollars (about 28.92 yuan), and with his parents' help bought more hens. Now he keeps 120 hens on the family's one-hectare property in Gerringong, in the southern district of Wollongong.
Calvin loves his hens very much, saying "They make me feel I have a lot of responsibility and a lot of things to do. I have to feed them, and recently they have started hatching eggs too." "In the morning I usually do some work before going to school. I feed the chickens, help refill their water and make sure they are all doing well. In the afternoon I refill their water again and feed them -- for example, some discarded vegetable leaves from the vegetable garden -- and every week I collect the eggs, pack them all up and put them in cardboard boxes."
Although there are too many hens to give them all names, Calvin and his 6-year-old brother Roxy have still named a few of them, such as Bronte, Golden Girl and Golden Boy.
Calvin does business in a different way. Each time he picks out one egg from a box and introduces to coffee shop owners how his eggs differ from competitors' products. Calvin's Eggs now supplies 30 cartons of eggs to three local cafes, so Calvin can earn about 100 Australian dollars (about 578 yuan) a week.
Vanessa said: "We are teaching him some business principles. I am very proud, he is doing very well." "I really see him in a new light. He has also taken the initiative to learn some knowledge about raising hens, and the eggs his hens lay are all very good." But for Calvin, he does not do this to make money. When his hens no longer lay eggs, he will let them begin their "retirement" life, because he does not plan to kill the hens. "Although having a bit more pocket money is really nice, the hens are all great, and I can't bear to part with them."
