I'm a first time chicken owner and I don't know how to tell the difference between a male or female. Also I'm not sure if my chicks are even the correct breed. Any advice would be helpful. I'm suppose to have 3 hens a barred rock light brahma and a buff Orpington 4 going on 5 weeks old. I have done research to try and figure out the gender and breed but I can't seem to decide on either. Any advice?
