When I was a child, I brought up baby chicks, I cared for chicks took in light bulb for heater at chill night, looked all day at beautifully grown chicken though, after all a cat killed them hideously.
I observed chicken early in the morning in India by chance when I traveled in South India, and felt spirit of creature to it.
On looking back it’s history, chicken is a creature raised for of human purpose by zoo-technology, that kind of animals are fragile for disease.
That why I prefers chicken for motif, because chicken is a metaphor of fragility for me, but free.
