Years ago, i rescued a chicken from the next door neigbours, They were an indian family and the guy had bought home a LIVE chichen for dinner, somehow between getting its head chopped off, it managed to get into my garden, I only knew about it when the guy came round from next door with a 6 inch carving knife and a plastic bag, wanting his chicken.
In the end i gave him ?5, and i kept the Chicken myself, Built it a little pen at the bottom of my garden and had it for about 2 or 3 years before it passed away natually.
I called it "Cocky"

poor little thing, i remember buying sweetcorn for it
Lived its last few years in super comfort, poor little thing
