4. How to Secure Fertility in Eggs. 



A following out of the suggestions here given, in prin- 

 ciple at least, is bound to bring success in securing fertile 

 eggs. 



It is absolutely necessary to have the male and female 

 of the proper sort. To" be such they should possess the 

 following characteristics. 



The male should be of medium size — in accordance with 

 the class, of fowl — strong, healthy, vigorous and active. He 

 should be such as is attentive to all the females of his 

 flock. It frequently happens that a cock bird takes a par- 

 ticular fancy to certain females. This should be watched, 

 and when found to be the case remedied by a change. Re- 

 member that with age cock birds, as well as other males of 

 the animal kingdom, become useless for breeding purposes. 



The female should also be of medium size and possess 

 a strong, healthy physical make-up. Pullets a year old to 

 two years of age are better than those younger or hens that 

 are older, for egg production for breeding purposes.
