Has anyone used this method for determining if your flock will be high or low production? I just finished reading "The Call of the Hen" online, and found it fascinating. I plan to implement it into my breeding program right away. The great part is, using this method I can work on egg production and the APA standard at the same time. While I found the book the kind I had to go back and check a few times before I was able to follow it completely, I found the method was very accurate about the flock I currently have. Would love to hear back from others who use this method. And if you don't use it, check it out!
