Hey y'all. I'm wondering your thoughts on my 20 week old (plus 2 days) Black Austrolorp. This is my first flock of chickens so im new to raising them but I'm thinking she's a he even though it was sold to me as a girl. (At one day old, from my local feed store) I have another Austrolorp that I'm certain is a girl. ( Ill post her picture first) It hasn't started crowing yet so I can't go on that. Can the same breed develop so differently? Any thoughts would be appreciated. Hen or Roo? Thank you!
