Well you all know I had 10 chicks hatch 19 days ago.. Well I think I can sex three of them as roos. Of the sussex chicks, three have more predominant tail feathers. I checked one of them close up and it's wattles look slighty pinkish. The others have yellow wattles, if you can call them that at the moment. The Orpingtons have no tail feathers like the other sussex. So I'm betting I have three sussex roos, three sussex pullets, and four orpington pullets. I'll try for pictures tomorrow.
