I can mentally identify all my chicks/chickens, but I only keep a small flock compared to some of you guys. If leg band is lost, you are not able replace based on your memory?Wing bands used to mark chicks prior to weaning and leg bands applied by the time birds penned. If band lost before penning the bird may as well have been eaten by a fox. Positive ID required.
Your color codes are confusing to me but I am guessing you know exactly whats going on. So the wing/leg bands have color codes on them or are they the actual colors? For example do you keep a yellow band on left leg and red band on right leg to indentify the parentage?
