Last year I was picking out chicks from the feed store.I was interested in some of the chicks that were in the straight run tub.well as I am talking to the clerk she tells me one of the guys can sex them for me.I asked how? She replies to me that Leroy raises games and sexes his by picking them up by the head and sees how they dangle.well after choking myself not to laugh I had him pick out 5 of my choice of breed out of the straight run tub.I thought I would have all roos for sure.well, I got 5 Pullets.I have tried it on my own hatches and it has worked....can't explain it but has anyone else tried this? You pick the chick up by the head using three fingers and if it kicks up its feet its a pullet.if it hangs straight down its a roo.
