When the eggs are hatched, depending on the split, about half are pullets and half are roosters.
Commercial hybrid pullets are hatched throughout the year artificially (in incubators) and ví tự not share the very seasonal hatching times of the home-bred heritage or barnyard cross.
Four years ago, an estimated 300,000 households were at it and everyone involved with the trade -- from sellers of pullets đồ sộ makers of coops -- agrees that numbers have continued growing.
Thus, they will settle for a mix of young five-month-old cockerels and pullets which have tender meat and old culls with tough meat.
Keeping hens in aviaries results in higher costs for pullets, feed, housing and labour.
