Do not (unless in exceptional cases w-here the specimen issufficiently valuable to take the risk of possible failure) usebreeders of either sex older than two-year-olds—that is, birdsolder than about tliirty months at the beginning of the breed-ing season. Right here it will Ijc well to differentiate the terms appliedto breeding birds, both male and female. A pullet is usually 17 ARTIFICIAL INCUBATING AND BROODING. 7—RHODE ISLAND RED BREEDERS spoken of as such until she has passed through one year of laying(her pullet year) or until she is about eighteen months old, whenshe becomes a yearling hen, which term applies until she haspassed her second year as a layer and becomes a two-year-oldhen. A cockerel remains such until he has passed his cockerelyear or until about eighteen months old—assuming that he be-gan developing his adult plimiage by the time he was six months■old. He is then considered as a yearling cock until the close ofthe second breeding season after he reached maturity,- when heis rated as a two-year-old. These terms are used in this senseonly when applied to breeding birds. NUMBER OF FEMALES TO A MALE The number of females which may be mated with a cock orcockerel depends largely on existing conditions. Commonly tenfemales is considered a sufficient number for a cock and fifteenfor a cockerel. This rule has many exceptions. Some males ar
