To date, there is no reported standard mating ratio for Nigerian native chickens despite their large population in the country. This study investigated the effect of mating ratio on behaviour, semen quality and level of stress. Sixty three (nine cocks and fifty four hens) sexually matured birds were randomly assigned to three mating ratios (MR) of 1 cock to 3 hens (1C3H), 1 cock to 6 hens (1C6H) and 1 cock to 9 hens (1C9H), each MR was replicated three times. Each cock spent two weeks in a particular MR before it was moved to another.
