Hello all! I am new to the forum and this is my first post. I have been raising chickens for 30 years, and never needed help with chickens until now!. I have 10 RI Reds & 15 Barred Rock chicks that are 7 weeks old (ordered from McMurray) and a surprise chick (pretty sure a rooster because he is trying to crow already, and not doing a very good job, yet). Could anyone tell me what breed of chicken this is? Thanks in advance.
