As in the two years I have been managing the breeding season by an Excel table, introducing She put the data in each pairing, such tables around the net and we can all get off at different sites on this hobby. In this table, in addition to the common data: put, numbers of eggs, babies, and rings. ... I added a spreadsheet to obtain the percentages of the totals, so I can scale as a percentage as the season has gone, in addition to this, I generate a table to qualify relying on the following values: 
0% to 25% - Bad
50% to 75% - Good
75% to 90% - Very Good
90% to 100 % - Excellent
absence of two couples who are still raising the numbers to throw this table are applied to the following 18 posts by 5 pairs of canaries in the following varieties: Bells, Brunos, Agate and Opal, and discarding the pairs of hybrids because of its complexity for breeding.
Females laid a total of 75 eggs, of which 85% were stepped on.
14% of the eggs were clear and 1% appeared broken.
Of the stepped hatched by 89%, the rest did not come to birth.
Of those who were born is girdled by 93%, 7% do not get eight days of life.
ringed the total of 96% were raised and now they are already independent.
Whereupon and in view of the data could be considered
season as "excellent" given the number of chicks ringed and bred, and as "Very Good" regarding fertility parents.
