The abdominal region is enlarged in the layer, as compared 'n'ith the non-layer. The pehic bones move ajiart and become eom])arati\el>' elastic and ])Hablc. In an individual that is not laying, these bones almost conic togetlier just below the \ent. The same iiidi\'idual when in full la\'ing may show a distance of three or e\ en four hnger widtlis between them. The distance from the pehic bones to tlie i)oint of the keel (breast bone) is increased at the same time. These changes provide room for the jiassage of the egg, the enormous increase in the size of the ovary witli its se\eral ra])idly growing ova and for tlie distention of the ahnieiitary tract to accommotlate large am(.)unts of feed. The hea\iness of i>roduetion is indicateil in a measure by the relative softness and jjliabiiity of the skin and the thinness.
