POINT OF VIEW ON LIVE-STOCK PROBLEMS 237 



ket eggs, it would appear best to keep her as long as she 

 lives. However, if eggs from such stock are worth so much 

 to sell for breeding purposes that the average price of all 

 her eggs sold is 60 cents a dozen, then the old hen should 

 go when her egg production falls 3 dozen below the pullet. 

 This would probably be two or three years. 



DEPRECIATION ON HENS THAT HAVE A MEAT VALUE OF 40 CENTS 

 AND A DEATH RATE OF 12 PER CENT 



The price of eggs, the price at which old hens are sold, 

 the relative value of old and young hens for breeding pur- 

 poses, and various other factors, affect the results. The 

 above discussion shows the method of figuring.

158. Increasing value of valuable young stock usually 

 more than offsets depreciation. The young stock from 

 valuable animals usually rises in price fast enough to more 

 than make up for the high depreciation on their parents.
