I guess the following pictures show exactly what they meant by this answer:
The boys have started chicken-farming. Instead of using the 5 Bhat coin we give them for school snack every morning, they have saved up their pocket money and bought themselves chickens! Now they are all busy building chicken cages, and we're quite impressed by what they have done so far! (PS: We are taking all the percations regarding the bird flu!!) 

Ha, ha! Some of the boys are so committed they even take tehir afternoon nap at the chicken-cage!
Today's catch!
Other children prepare 'makhang' for cooking.
