However, once the industry successfully bred separate meat and egg-producing hybrids—starting in the 1920s and 1930s [10] —there was no reason to keep males of the egg-producing hybrid. As a consequence, the males of egg-laying chickens are killed as soon as possible after hatching and sexing to reduce financial losses incurred by the breeder.
The short legs of creeper chickens are the result of autosomal dominant transmission of a lethal allele, Cp. Affected birds are heterozygous (Cp/+) for the gene; homozygotes (Cp/Cp) die at the embryo stage. [11]: 2 [12] The Cp trait is linked closely to the gene for the rose comb, MNR2. [11]: 2

Older hens gradually produce fewer eggs, and the eggs are usually larger. [1] Since the average lifespan of a pet layer hen is 8–15 years, [2] henopause has received attention as a potential problem for backyard or urban chicken farmers who are eventually faced with the decision to either slaughter older layers or keep them as non-producing pets.
