As the energy level decreases in ration, chickens head for increasing their feed consumption and by this way satisfying their energy needs. Because of the scarcity of the amount of feeders and limited feeding for the studs, animals can not produce sufficient energy for themselves. Both the immensity and the amount of the eggs decrease for those mature animals which consume the feeds that include less energy. In such situations, infertility can be observed for the stud roosters, fallen zippy gravity can be observed for the stud chickens, cessation of the growth of chicks and reduction of these chicks’ body tank oils. There are not seen any other indications as long as the ration energy is sufficient enough to live. Otherwise loss in weight begins and energy need for living is not going to be satisfied. This situation continues until death by falling down to provide some more energy and use the out of pocket stored glycogen.
