Thank you for the response Fred. I can live with it being a mix as long as she is a hen. A roo will have to go before he starts crowing. Would you say Roo or Hen?
Let me add that she/he does not appear to be crowing or trying to crow, but is way larger than any of the others (2EE&RR) that have the same hatch date.
The photo is of Roxy an approximately18 week old barred rock supposedly sexed at hatching. I'm starting to wonder if she is actually a he since "she" is bigger than my 1.5 year old leg horn and red star hens. What do you think is it a Hen or a Roo?
