Well, they are all around 4-6 weeks old I think. We have 14 total which were all bought at TSC. I only want to keep one rooster and am afraid that I ended up with much more. I have never raised birds and don't know what signs to look for with each breed to determine sex. I have heard that you just have to wait until they start crowing but surely there is something sooner than that. These are the ones I am really concerned about because they are so beautiful: I would like to keep one of these because they are so massive, I would think that a huge male would do more to protect the flock if a predator became a threat. Am I wrong? Here is one of two big'uns: And of course, an overal pic of them huddled up for sleepy time: Thanks for any help you can offer!! -Steve ps. I know that there is no such thing as a "battle chicken", but if one can fight long enough to make me aware of a problem then I am willing to sacrifice the biggest "battle chicken" available.
