Comparisons of a Midget vs. a Standard Sized Strain of Laying Hens

Two new strains, one standard sized and the other approximately 70% as large, were acquired and tested for performance. The chicks were grown in floor pens to 20 weeks of age on standard growing diets and then placed in 12- and 16-inch layer cages. The hens were placed in cages at normal and high density, i.e., 3 or 4 hens per 12-inch cage and 4 or 5 hens per 16-inch cage. All were fed the same diet, 16% crude protein and 2900 Gal. M.E. The test lasted 10 months
