After hatching, chicks are vaccinated, and may be debeaked and sexed before placing in the houses. Debeaking has been largely replaced by good management. Purpose is to reduce cannibalism and downgrading caused by pecking.
Many companies grow broilers separately by sex where customers desire a wide range of sizes.
Sexing is by color or speed of feather growth. After processing in the hatchery, chicks are placed in plastic chick boxes at the rate of 100 per box. Chicks are transported to the house in specially designed chick buses. Buses must maintain comfortable temperatures inside while providing good ventilation. Backup systems are essential in case the bus engine fails during delivery.
