TLDR
An attempt was made to find out whether there was any selective preference in the union of sperm and egg cells in poultry, and it was found that self-fertilization was more effective or easier to make than cross fertilization.About:

The Collection of Spermatozoa from the Domestic Fowl and Turkey
W. H. Burrows,J. P. Quinn +1 more
TL;DR: A number of methods for obtaining semen from the fowl have been described, including mating a cock to a hen and immediately securing the fluid from the cloaca of the hen.
Journal ArticleDOI
The effect of ratios and numbers of spermatozoa mixed from two males on proportions of offspring
TL;DR: It appears that the relationship between sperm ratios and the proportions of offspring sired by two males competing heterospermically is dependent on the ratio of the number of competing spermatozoa but not on total number, season, breed of hen or the interval from insemination to fertilization.
Journal ArticleDOI
Studies of sperm competition in two species of muroid rodents
TL;DR: Results suggest that effects of mating order are highly species-specific and must be evaluated for each species before speculations are made regarding the effects of multiple matings, and females of the brown-recessive genotype mated with one male are only slightly less likely to become pregnant than wild-type females.
Journal ArticleDOI
The Relationship of in Vivo Sperm Storage Interval to Fertility and Embryonic Survival in the Chicken
TL;DR: The effect of time after insemination on fertility and embryonic loss has been studied for each day’s egg production by direct observation of chicken eggs after 18 days of incubation, showing a significant initial increase in fertility with sperm storage from day I (first day of fertileeggs) to day 3, followed by a few days of high fertility which was then followedby a linear decline through 18 days.

Competitive Fertilization in the Fowl
C. J. Allen,L. R. Champion +1 more
TL;DR: One of the major economic losses in the field of poultry husbandry is the large numbers of infertile eggs among eggs produced for hatching purposes.
