Cockerels shouldn’t be introduced until pullets are not less than 18 weeks of age and young males no less than 24 weeks of age. In the act of mating, the semen in the reproductive cells of the cockerel is ejaculated into the cloaca of the hen and travels up by means of the oviduct to unite with the egg yolk (ovum) shortly after it leaves the ovary.

Enough semen swims up to fertilize between 12 and 14 eggs at one mating; this permits a younger vigorous cockerel to cover successfully as many as 80 hens in a flock, although I do not advocate this as standard procedure.

For out of doors breeding, good fertilization is achieved with one cockerel per 25 birds. If 100 breeding hens are running together as on flock, it’s advisable to put in 5 or 6 cockerels, ideally these which have been reared together. It’s not practical so as to add any further cockerels at a later date ought to any loss be incurred: as these would be attacked and possibly killed. By staring with one or [two] further cockerels within the pen, the breeder is able to run successfully by means of the breeding season even when one or [two] cockerels die or lose conditions. Cockerels can at all times be taken out however by no means added.

On observation, until there are a lot of hidden areas for all cockerels to work without interference from each other, then the one on the prime of the peck order will do the vast majority of the work, with the second in line protecting the remainder of the hens, Ought to too many cockerels be put in a pen of chickens, they may spend most of their time pushing one another off each time one tries to mount, and fertility shall be adversely affected. The place birds are paired, one male to one female, fertility is usually very poor. It is much better to pen one male to six females or extra, for good incubation results.

Cockerels being reared collectively as stock cockerels will from about fourteen weeks of age being to say their sexual authority, resulting in the one at the backside of the peck order being habitually raped. If this fowl is taken away, then the next can be trodden and so on. To alleviate the issue, some breeders will put in an older male, one of the earlier 12 months’s birds as this generally helps in maintaining the younger birds below control. The other method is to run [two] or three of the older hens not required for breeding with them. It not only prevents the cockerels from attacking each other, but gives them mandatory experience before they’re introduced to the breeding pen.

Finally, when a pen is made up of one male to several females, it is generally found that one or [two] chickens will not be fertile. This may be as a result of they don’t seem to be compatible with this explicit cockerel. Where a couple of cockerel is utilized in a pen, offering pen numbers are ample, this drawback is decreased, if not resolved. The opposite various is to separate infertile hens, inserting them in one other pen with a unique male, who may be discovered to be compatible.
