Diseases, predators, and lack of care and food kill many chicks. 

10. Very often out of 15 chicks that are hatched there remains at the end of a year only one sound chicken. The others - 14 out of 15 - are either dead or sick or too small. 

11. They yield little meat for the villagers ... 

Very often the animals, even those more than two years old, remain small and yield very little meat. So that on feast days and at funerals, for instance, a lot of animals have to be killed to get enough meat. 

12.... or for the country 

The country has to buy abroad good meat to feed the people in the towns. 

So it loves a lot of money. 

The money used to buy meat abroad cannot be used to make roads, build schools, or pay for nurses and medicines. 

Enough good meat must be produced so that the country does not have to buy it abroad. 

13. They yield little money 

The hens and chickens are too small to be sold at a good price. 

All the chickens that are dead or sick have been fed for nothing. 

All the remains of food or of the harvest eaten by these animals have brought the farmer nothing. 

The farmer has spent very little, but he has not earned all the money that he might get with his livestock.
