Relation of Avian Egg Weight to Body Weight

The Auk, 1975
JUST over 50 years ago Heinroth (1922) published the first extensive list of egg weights and adult body weights for 427 species of birds. Since then additional data have appeared and the most extensive list can now be found in Schonwetter's (1960-72) monumental description of bird eggs.

The relationships between egg weight and yolk weight

British Poultry Science, 1964
Synopsis Figures on egg weight and yolk weight from a commercial strain of White Leghorn pullets obtained during the early part of their laying year have been analysed to obtain estimates of heritability and phenotypic, genotypic and environmental correlations.

Egg Production and Egg Weight Standards for Table-Egg Layers

2002
Egg production and egg weight are two of the more important measures of performance for egg-type chickens. Standards are important tools for judging the success of rearing programs and adult flock management programs.

Yolk concentrations of hormones and glucose and egg weight and egg dimensions in unincubated chicken eggs, in relation to egg sex and hen body weight

General and Comparative Endocrinology, 2013
Birds can manipulate offspring sex ratio under natural and experimental conditions and maternal hormones have been shown to be involved in this process. Studies also provided evidence for the presence of sex specific concentrations of yolk hormones in avian eggs.

The effect of variation in egg numbers, body weight and egg weight upon shell thickness

British Poultry Science, 1972
Synopsis It is expected that when birds consume a diet with a fixed calcium content variation in the rate of egg production, in body weight or in egg weight will lead to variation in calcium consumption. This analysis investigated whether, in a particular experiment, this also led to variation in egg shell thickness.
