I have a little game banty that I cant decide if its a hen or roo.. I was told that it was a roo. it has no comb to speak of, no spurs. it has crowed according to the person I got it from. it killed 3 baby cochins. I think that its a hen because one day I was cleaning the coop and I moved my hand in its direction and it squatted. I then caught it in a nest box fluffin up the hay... I cant tell if it is laying or not... so I might have to segregate it from every one else to find out!
