I pinioned at 3 weeks. I had their cage clean and ready, and I had them in a box and quickly took out the quail one by one, hubby snipped with meat shears, and I put them in the clean cage. Which quickly became bloody. But they quit bleeding fairly soon and I kept the light on them to keep them from going into shock. I lost the smallest one. I didn't even look at them, I think they had enough of me. I was able to clean them out the following week. I didn't even bother pinioning the whites because they were so skittish I thought it would kill them, they'd bleed out too fast. plus there is only 6 of them and if they don't get to size I'll eat them. this next batch i will pinion after next week.
