Tales of Strange Chickens--taken from the PasturePoultry Group on Yahoo
(I doubt they were Cornish Crosses.
A few years ago several chickens fell out of a truck hauling them to slaughter. They ended up living in the median of I-5 near an overpass. Since there was room to pull over, people started to put out food and water for them. They lived there happily for months. I don't know if they were finally picked up or got squished; the highway department wanted them gone because locals would slow down to look for them and they were a traffic hazard. And the highway department guys are locals, too, so I am guessing they caught them. I never saw them squished, and they were big birds when they grew up - Cornish crosses.
