      A great book to check out The Hatchability of Chicken Eggs as Influenced by Environment and Heredity by Walter Landauer It is for chickens but quail . The aim of this study was to predict hatchability using external egg quality traits. Seven hundred and twenty eggs were collected from inbred populations of three strains of layer-type chickens comprising of two exotic strains: Black Olympia (BO), H and N brown nick (H and N) and the Nigerian Local Chicken (NLC) at 40 weeks of age.

    Chicken Egg Hatchability Problems Part I There are a number of problems that can arise for the hatch ability of eggs, though they will typically be problems with the hatchery, the handling of the eggs.   The gassing should be done as soon as the paint is dry and with the incubator operating at recommended temperature and humidity for incubating CANDLING:Candling chicken eggs on the 7th and 18th day of incubation, may be recommended for small poultry producers. Egg candling will detect infertiles and early dead germs.

    Broiler hatching eggs from two young (30 and 31 wk) or two old (52 and 53 wk) breeder flocks were stored for 3, 7, or 14 d at 18 C and 75% RH while being turned 0, 4, or 24 times per day in two experiments. Apparent fertility and hatchability of total eggs differed with flock age in both experiments, but the effect was greater in Experiment 1. egg production, mortality, morbidity, egg weight, shell quality, hatchability, feed consumption, and antibody titers) and the egg history from the nest through the hatchery are essential in providing clues to most hatchability problems. Personnel should be trained in recognizing problems, identifying causes.

T h e Hatchability of Chicken Eggs as Influenced by Diallel Crossing NELSON F. WATERS, Senior Geneticist U. Regional Poultry Research Laboratory, East Lansing, Michigan (Received for publication Ap ) T HE ability of fertile chicken eggs to hatch is dependent upon many genetic and environmental variables which have been adequately presented by Landauer ().Cited by: 1.

Equally important is the micro-environment surrounding the eggs prior to incubation. Egg collection, storage, and handling must be optimum to maintain embryonic viability before and during incubation. After setting in the incubator, temperature, turning, humidity, ventilation in the incubators and incubator rooms, sanitation, and general hatchery management are all critical factors to ensure embryonic survival and hatchability.

Hatchability of Chicken Eggs as Influenced by Environment and Heredity, The. By Walter Landauer. Topics: hatchability, chicken eggs, environmental, heredity Author: Walter Landauer. A large number of eggs from a mass-mated flock of Single Comb White Leghorn pullets were candled and eggs containing only one defect were retained for hatchability trials, normal eggs being used as controls.

The average hatchability of the defective eggs was per cent. of the fertile eggs; for normal eggs it was per cent. Poor shells and loose air cells were the chief causes of poor.

In eggs from the same flock between 48 and 60 weeks of age hatchability was depressed by 1 percentage unit with each increase in RH from to 6. Eggs from a young flock (34–49 weeks) hatched significantly better when maintained at rather than at (P.

The hatchability of the fertile eggs ( ± %) and the hatchability of the set eggs ( ± %) were negatively affected by the application of ethanolic extract of propolis.
