Boxes of chicks, retailer vintage studio photo

This photo is in great condition, there is one crease along the top as well as some rippling. I've included a scan of the writing on the back as most of it I can not make out. Based on other photos I found this with it retailer appears to be from a chicken farm in California. This is a very unusual studio photo shot, you're unlikely to find another like it. Sold as is.
