THE ROLLER CANARY 27 
every breeder who wishes to keep accurate records will 
avail himself of the help it gives. 
The daily happenings in the stud may be noted in 
a small memorandum book or a card chart, and then 
transferred to the Stock Book once a week, or at 
such intervals as are convenient. 
- Beyond its value as a record of the pedigree of every 
bird in the stud at any given moment, past or present, 
it is deeply interesting, and very helpful, in many ways. 
It will show all the pairings, with ring numbers of old 
and young, dates of mating, laying, and hatching, 
together with the results of each nest, of each pair, and 
the whole stud for the season. If properly kept, it will 
contain records of all sensational birds, all birds that 
have been afflicted with illness, and also those that have 
died either from accidents or disease. 
All records in connection with the pedigree of each 
bird should be entered fully into the Stock Book, so that 
a quick reference can be made if required. A small 
book should be prepared, or a breeding chart should be 
made. The most convenient form is a large thick piece 
of white cardboard; this can be ruled to provide a 
column for each cage, allowing space for three nests 
from each pair of birds. The ring numbers of both 
male and female should be placed in the first square, and 
as the work of the season progresses, notes can be made 
in the respective columns regarding results from each 
pair, such as time set, time due to hatch, number of 
young birds hatched, and number raised, together with 
the ring numbers of the young birds themselves, in each 
succeeding nest. Later, all these particulars can be 
entered in the Stud Register, which becomes a permanent 
record of each year’s work.
