I have 6 cochin chicks that I recently aquired, and I had some questions for the experts out there. They're 4 weeks old, I think I have a black, two blue, and three splash. Is there a difference between the standard and giant cochins? Or are they the same thing? Also, what are considered good and bad qualities? I thought I saw something about the types of feathers on their legs. I'm clueless about this breed...
