Just speculating here. I'm guessing your granddaddy didn't pamper his chickens or read for hours on backyardchickens.com about inventions, tips and tricks to keep your chickens cool. And maybe his chickens just suffered through the heat and occasionally maybe one or two actually died from it. But that was simply a seasonal and accepted loss, not the tragic loss of a cherished family pet. Maybe they just thought of their chickens differently than we do these days.
The old man who lived next door to me and kept the same sorts of chickens that I do thought I was out of my mind for putting an automatic door on my chicken coop, although I think he secretly liked it. And he scoffed at me for putting a chunk of ice in the chickens' water can. Different generation, different way of looking at things.
My grand daddy discussed for hours each weak with a much smaller social group face to about his gamefowl. Grandmother did most of her correspondence around church meetings and evidently through the mail.
