The mating and breeding of poultry . st commonly done by toe punching the chicks from eachmating with a distinctive mark. Chick leg bands may beused for this purpose if desired, but toe punching is simpleand answers the purpose very well. There is a tendency forsome of the toe punches to grow up, and to make sure thatthis does not occur and thereby confuse the record thechicks should be gone over carefully when about two weeksold, and any holes which show a tendency to grow uppunched out anew. This second punch, if necessary isalmost certain to be permanent. See Fig. 13 The-e penpedigrees tell

Where pedigree records are desired which will give theparentage on both the male and female side, it is necessaryto resort to a more complicated system of records, exceptwhere the matings are few and the individual hens of all thematings involved do not exceed 16 in number. For anynumber of hens up to 16 a different toe punch can be giventhe chicks from each S?hatchS^^ ?Pv!nt™K^ )^ ^.t^^ pedigree basket and bag ready lor hatching.

Trapnesting is the first requirement of complete pedigree-ing in order to be able to identify the eggs from each eggs should be marked, preferably on the large end,with the number of the hen, and if desired, with the pennumber as well. Sometimes the system is used of writing 42 THE MATING AND BREEDING OF POULTRY the pen number, then drawing a Hne and beneath writing the hen number, e. g. 9/ 9 being the pen number and 36 the hen number. If the eggs are to be incubated under hens,enough must be saved from an individual hen for a sitting,or eggs from two or more hens of different breeds may beused to make up a sitting. If they are to be hatched in in-cubators, eggs from the different hens are placed in themachine together. On the eighteenth day the eggs from each hen are sorted
