Hi, I am raising some straight-run Black Langshans. They are two weeks old. I'm not sure how many are roosters, but we're planning to eat those ones. Anyway, I need to have them processed before they start crowing (because of neighbour). When is the best time to have them processed? Also, I'm wondering if they do, indeed, have yellow flesh. I couldn't find much on the Internet about that. My hen is very black (feathers, legs, and beak), so I'm concerned that their flesh will be black too. Thanks for your help.
