Hi, I have one chick. She came from my flock. I am not very educated with chicken breeds, but I have a rir, 2 isa browns, 1 isa black (is that an actual breed?), 1 isa white and a bantam. Baby hatched from a large light brown egg. I am not really sure about my rooster's breed. I have some pictures of him, hopefully so we can discover what breed Baby is. The chick has blue/grey back feathers and legs. She also has some white and black wing feathers. I feather sexed on day 1 and she was a girl, but now I am hearing it isn't accurate. Please help me. Thank you.
