I believe they start about mid way down the back, but I'd check higher up if you're unsure just in case. Iirc they should start mid way up the back and eventually be long enough to flow off the body in the classic saddle shapeHi! Just another question as I was looking at my older rooster today. Do they first form from halfway down the back along the spine? Do they go all the way to the tail or stop before it? I think I was looking too close to the tail...
