PROFITABLE POULTRY PRODUCTION 



the original cock in group i, and 3-32 of the blood 

 of the hen in group 2. 



From the foregoing discussion it is evident that 

 great care must be exercised to prevent breaking 

 up the system of breeding; for by carelessness all 

 the good results may be lost, since the progeny will 

 be thrown back into one family and thus indis- 

 criminate breeding result in ultimately spoiling the 

 flock. It is highly desir- 

 able, therefore, that the 

 plan be definitely laid out 

 beforehand and followed 

 without deviation in any 

 respect. If the best re- 

 sults are to be attained, 

 the chart should be made 

 and its tracings followed 

 systematically from year 

 to year. Without the aid 

 of the chart careless 

 breeding is sure to result 

 and the whole system be 

 spoiled by injudicious 

 matings. If the lines of 

 the chart are carefully 

 studied and followed, a 

 great improvement may 

 be shown in the ordinary 

 farm flock as instanced 

 alx3ve. Thus flocks may 

 be made more profitable 

 at the cost of only a 

 little thought and care. 



There is only one more caution to be made and 

 that will be guessed from other portions of this
