I think it's in our genes. Chickens have been domesticated for a long time. Those who kept chickens were surely healthier and happier than those who did not. Therefor they lived to reproduce and pass on their chicken loving genes. chickens connect us to our ancestors. I read a journal my grandmother kept. In it, she tallied the number of eggs she collected each day, or how many she sold to the country store. She noted when chicks came in the mail. And she noted the first time she herself bought eggs after she retired and moved off the farm. I feel a connection to the woman who died long before I was born through our mutual interest in chickens.
