"baby turkeys" thats cute... " Poults" as they are officially known, and there is a way to tell, but you have to squeeze the S*** out of them to tell if they are male or female, similar to chickens. I think by nature, they are born 52/48 % male/female because of the higher mortality rates in males, due to fighting, hunting, and other things... That means out of a 100 poults hatched, 52will be male, 48 will be female... Nice picture though.
below is one I got of some, hard to see, but some of them are jumping/flying out of the ditch...
