I will be allowing my chicks full use of their run in a couple of weeks. As of now, it is not covered and I know they can fly. So, do I clip their wings? Do most people clip? When do I clip? How do I clip? And while I'm asking questions; 1) Can someone tell me what are saddle feathers and what about them tells the sex of a bird? 2) Can I have all hens, will I be able to add a roo at a later date? Thanks for any input!
