Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. L’autora del treball ha tingut la possibilitat d’estudiar de prop una comunitat de gallines d’una raça concreta: Gallina nana flor d’ametller. La seva curiositat l’ha conduït a portar a l'Escola uns ous fecundats deixant la resta de la posta amb la gallina. Així comença l’estudi que té com objectiu establir similituds i diferències entre la cria natural i l’artificial en una incubadora. Posteriorment, aquest treball s’ha completat amb la comparació d’uns exemplars concrets de pollets de la raça estudiada. S’arriba clarament al final del treball a unes conclusions molt concretes: resulta molt difícil igualar de forma artificial allò que a la natura sembla que es realitza amb tanta facilitat. Per això es conclou taxativament que 'la natura és sàvia’.

Research project carried out by a pupil of secondary education and rewarded with a Prize CIRIT to foster the scientific spirit of the Youth in year 2009. The author of the work has had the possibility to study a community of hens of a concrete race: a Catalan hen called 'la gallina Nana de Flor d’Ametller '. Some fertilized eggs have attempted to incubate artificially, while the rest has been left with the hen. The study starts establishing similarities and differences between the natural breeding and the artificial one in an incubator. Later, this work has been completed with the comparison of some concrete specimens of chicks of the studied race. Some very concrete conclusions are reached clearly in the end of the work: it is very difficult to equal in an artificial way things that in the nature it seems is carried out with facility. Because of that, it is concluded specifically that 'the nature is wise'.
