This story isn't RV related but it is chicken related. Beginning in 1967 I beat I30 between Dallas and Commerce where I went to college. It was common to see flatbed semis loaded with crates of chickens. There were always feathers along the road.
I think this incident happened about 1968. I was coming home on Friday and topped a hill near Rockwall. A semi load of chicken had dumped about half of its load in the middle of the highway and another semi or two had ploughed into the crates. This must have happened just minutes before I drove through the carnage. There were dead chickens everywhere. There were chickens flopping around in the process of dying and live chickens running back and forth across the road.
I couldn't avoid running through the mess. When I got home there was chicken blood and feathers stuck in the grill. For weeks you could drive past where the accident happened and there were chicken feather caught in the vegetation along the road.
