Martin and his Chook

This is Martin my mate, we have been friends for over 50 years and we worked in the same profession together for nearly 30 years. The chook I only know for a short period of time. This chook wandered into his place about 9 months ago. No neighbours have chooks. This hen follows Martin all over the yard and his shed. To day it was monstered by big dog.
After the dog was chased away the chook perched herself on his knee and did not move. The poor thing had an avian version of heart attack.
