A childhood belief about birds

I come from a southern family and there are a lot of sayings that i took very literally as a child. When my grandfather would call me out of the rain he would say that I was oigng to drown like a turkey. He claimed that a turkey would drown in the rain if turkey farmers didn't bring them in because they were so dumb that they would look up to see what was hitting them in the head. I believed this up until I was in college! I was stating this rare fact that i had to a firend (I found out it was rare because no one I had ever told had already known it) when my friend said "Well, there are wild turkeys aren't there?" and it shattered my belief.
