Scientific Agriculture, Vol. IX., No. 2, 1928.In this study of 569 records of first year production it was found that average production had increased by nearly twenty eggs or from 187 eggs in 1920–21 to 206 in 1925–26. The mean annual egg production of the 569 birds was 198 eggs which was practically identical with the average for Barred Rock pullets entered in the British Columbia contests. |
