Practical Stockmanship
If only farm records (growth, feed consumption, etc) are monitored, important signals from the birds and their environment will be missed. Using all the senses, the stockman must build-up an awareness of the environment, the birds' experience, and an understanding of what the normal behavioral characteristics of the flock are.
This information should be continuously analyzed (in conjunction with the farm records) to allow any shortfalls in the birds' condition and/or environment to be rapidly identified and corrected.
