Where the 90 birds were together they averaged 103 eggs 

 each, and where the 60 birds made up the flock, 109 eggs was 

 the average to each one. Where the larger number of birds 

 were together they did not appear to suffer from confinement 

 during winter, as only one bird was lost from November ist to 

 May 1st. 



In the pen where the 90 birds were kept, the floor space was 

 5.1 square feet per bird, and in the pen where the flock numbered 

 60 birds the floor space was 7.6 feet per bird. 



It is doubtful if there are other lines of investigation where 

 results are likely to be of greater value to practical poultrymen 

 than the study of sizes of flocks and floor spaces for birds. If 

 floor space can be as economically used by leaving it in one large
