Expert Response
Sexual maturity guinea hens appears to occur around 27-28 weeks of age with the onset of egg production, although there are reports of egg production starting as early as 21 weeks of age (Abdul-Rahmana, Jeffcoate, and Obese 2018). Higher oviduct and ovary weights have been reported for guinea hens kept on range versus those on deep litter or in battery cages (Oke et al. 2015). This may be an indication of accelerated rate of reproductive development on range. The hens on free-range also had higher liver weights which corresponded to the follicle recruitment. The liver is the main source of egg proteins and yolk materials.
