in the straw. TJiese results were secured with Leghorns. With two 

 other pens of Leghorns, during the first year as pullets the pen with 

 "exercise" laid 160 eggs, and the pen with "no exercise," 157 eggs. Dur- 

 ing the second year the "exercised" pen laid 119 and the "no exercise" 

 120, the results for the two years being practically the same for thos'^ 

 two pens. 



3. As to the effect of exercise on food consumption, the average 

 of pens 3 and 4 for three years shows that the pen with "exercise" con- 

 sumed 62.4 cents worth of food, and the pen "without exercise" 60.8. 

 In the case of two other pens the average was 63.5 cents and 62 cents^ 

 respectively, per fowl, in favor of "no exercise." 



4. During the year the Leghorns consumed an average of 62 cents 

 worth of food per fowl. The Wyandottes consumed 81.6 cents per fowl, 

 and two pens of Plymouth Rocks averaged 87.7 cents per fowl. 



5. The Leghorns consumed during the year an average of about 75 

 pounds of total food or about 55 pounds of dry matter per fowl; the 

 Wyandottes 100 pounds total food, 73 pounds dry matter, and the Plymouth 

 Rocks about 110 pounds total food and about 80 pounds dry matter. 



6. The three years' results from Leghorn pullets show an average 

 of 162 eggs per fowl per year at a food cost of 4.6 cents per dozen. These 

 results are not from selected or "pedigree" layers. 



7. The record of weights of fowls shows that Leghorns weigh about 

 ten per cent more during their second year than during the first year as 

 pullets. During the third year there is practically no incease in weight. 



8. The largest egg production was during the period of greatest 

 food consumption. The smallest egg yield was when the food con- 

 sumption was least. The hens attained their greatest weight immediately 

 preceding the periods of greatest egg production. After the periods of 

 heavy laying they showed a loss in weight. 



9. Five pens of Leghorns two and three years old laid eggs averag- 

 ing 1.56 pounds per dozen. Five pens of Leghorn pullets laid eggs aver- 

 aging 1.37 pounds per dozen. The eggs from the pen of Wyandotte 

 pullets averaged 1.56 pounds per dozen, and those laid by four pens of 

 Plymouth Rock pullets averaged 1.52 pounds per dozen. 



10. Eggs from different hens of the same breed varied in weight. 

 One pen of Leghorns two years old laid eggs averaging 1.45 pounds per 

 dozen. T,wo other pens of the same age, but of different strain, laid 

 eggs averaging 1.63 pounds per dozen. The eggs from the latter two 

 pens weighed more than those of the Plymouth Rock or Wyandotte 

 pullets. 



11. The eggs from five pens of Leghorn pullets averaged 1.44 pounds 

 per dozen. The eggs from the same pens during the second year averaged 

 1.54 pounds per dozen. In other words, the size of the eggs was eight 

 per cent greater the second year than the first. 



12. A test of wheat versus corn gave results in favor of wheat for 

 egg production. 



13. In the case of Leghorn pullets the addition of dried blood to 

 the ration considerably increases the egg yield. With Plymouth Rock
