Calmly and correctly handle birds placing them into the weighing vessel until it has the desired number of
birds in it (10-20 birds depending on the size of the vessel). Place the weighing vessel back onto the scales
(Figure 51), wait until it is still and record the bulk weight from the scale, before releasing the birds back into
the main house area. Repeat this process until ALL birds in the sample within the catching pen have been
weighed (this will eliminate any selective bias).
