[ 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 ...
Sex-links[1] are crossbred chickens whose color at hatching is differentiated by sex, thus making chick sexing an easier process. Sex-links come in several varieties. As hybrids of laying or dual-purpose breeds infused with extra vigor via heterosis, sex-links can be extremely good egg-layers which often produce 300 eggs a year or more ...
