Can someone tell if this Sex Link is a hen or rooster? I was told that it "should" be a hen. The breeder said, "You can tell it's a Rooster if he starts crowing".I have noticed that the comb and wattles have grown considerably in the last week or so. (this pic was 2 weeks ago, its comb and wattles are bit bigger and redder) In addition, It has been going head to head with Red (below) my RIR roo. Thanks for the help.
