Vent Lesion
Vent lesions can be an indicator of aggression within a flock. They are typically assessed using the catch and release method, however, if feather cover in this area is poor, the transect method may be used for assessment. While this measure is relatively rare, it can be used as an early indicator of aggression within a flock, as well as early detection of potential cannibalism outbreaks.
Basic Assessment: Occurrence
|
A normal vent region, as seen in the photo to the left, should have clear skin and no evidence of scratches, peck wounds, bruising, or scabs. This hen would be scored as NOT having vent lesions.
This photo shows bruising and a scratch just below the vent (indicated within the red circle). This hen would be scored as having vent lesions. |
