Well, for starters, it wasn't a chicken. It was someone dressed up in a chicken costume, a human sized chicken if you will. This dressed up human sized chicken was outside a school helping kids cross the road. It was in fact a lollipop man/woman dressed up in the chicken costume. Why was a lollipop man/woman dressed up as a chicken? Because it was National Dress Up As A Chicken Day for those employed in the lollipop industry.
My dog has got no nose. Yet, against all odds he managed to get gainful employment working as a sniffer dog. Fair play to him.
