I had heard of that as well, and it was 100% accurate with my chicks. Easter Eggers and Black Australorps.
Oh yeah, and to answer your question Gindee77- It is their wing feathers. If you pull their wings out and look at the lengths of the feathers (have you ever clipped a chickens wing? Just pull the wing out the same way as if you were going to clip it) when the feathers first start growing, you can see differences in lengths on them. I wish I had taken pictures! I can't remember for sure how old they were when I tried this, I am thinking about 4-6 days. May not work with silkies or frizzles though...
