It depends on which strategy I'm pursuing, but in Big Corn I like to get the 4th worker ASAP (preferably on a starting tile).Then pickup a 5th soon after the second food day to drop and leave on Chicken Pizza. I let him ride it as high as possible to use the skull I get from the temple reward on the third food day.
