hatching, rearing, housing and feeding being the same it was 
possible to arrive at a bird’s capacity as an egg-producer if hatched 
in March or April by the end of the same year. 
The point may now be further demonstrated by separating out 
the birds laying 1 to 9, 10 to 19, and 20 and over, eggs during the 
first three periods where each month commencing with November 
represents a period. Thus it will be seen from the following table 
that of the birds which laid in the first period those producing 
20 and over, 57 per cent. of these laid over 200 eggs during the 
competition, while of those producing 10 to 19 eggs only 26°6 per 
cent. laid over 200 eggs. 
In the second period only six birds laid 20 eggs or over, and of 
these only three produced 200 eggs, and the average of the birds 
which laid 10 to 19 eggs in this second period was 1644 although 
four birds laid 200 eggs in the ten months. 
Of the birds which commenced to lay in the third period, only two 
birds reached the 200 score, while the average was 151-92, and sub- 
sequent to this period the average yield per bird was only 105-64.
