Brooding

Male and female chicks are usually reared separately until about 4-5 weeks of age. They are then reared so that they can work out who is boss (adjust the peck order). They are then less likely to fight with one another later on.

Growing

The growing period for layer breeders is from five to 20 weeks of age. The growth period is about four weeks less than for meat breeders. During the growing period, feed is restricted to prevent feed wastage and, for layer breeders, to improve egg production. It is even more important for meat breeders because they become too fat to breed efficiently if on full feed. Restricted feeding begins at about six weeks of age and continues until birds have commenced laying. When birds are at 5-10% egg production, a breeder ration is supplied. Birds then have been gown on restricted feed are often call control fed.

Housing

Chickens reared for breeding purpose are usually raised on litter floors similar to those used for meat chickens. They are transferred to specially designed breeder sheds, also with litter floors, when about 18-22 weeks. The sheds are usually divided into small sections, suitable for about 200 hens to minimize fighting. Nests are placed in the shed, usually in the center, so that the hens are attracted to the dark areas of the nest to lay their eggs.

Mating

Cockerels will mate with a number of hens and about 10% of cockerels to a group of hens is enough to achieve excellent fertility rates. A surplus of cockerels (15%) is placed at first and they are culled down to 11% at maturity to allow a lost of 1% over their lives. Cockerels can be fed a cheaper diet than hens and it s a common practice to have additional cockerel feeders in a shed placed at a greater height than those containing hen feed.

Fertile eggs are collected as soon after laying as possible for reasons of hygiene (if left in nests they are more likely to have manure spread on them or be damaged). Regular collection also protects the eggs from the heat of the day. Although it is best not to clean eggs at all, eggs can be cleaned when collected by wiping with a dry cloth or steel wool. Wet cleaning is undesirable as it removed the protective cuticle from the shell. Fumigation by formaldehyde gas is carried out as soon as possible after collection, usually at the farm or sometimes at the hatchery.

Incubation and hatching

Eggs are set in trays marked with the shed of origin so that any problems can be traced back to the source. Hatching performance is also closely monitored and the end product is a healthy chick which goes on to become a commercial layer or meat chicken
