The chipmunk stripe chicks all have serious tails grown in. I'm going with the assumption that these will be like the FR were and they are males, the ones still without tails grown in or just starting to grow in assuming females.
The faint chipmunk stripe chicks look to be female. Feather leg chicks all three female. Blonde chicks look like 7 male and 4 female.

The spiral leg bands were a pain, I had to pull and unwrap them off. Won't get those again. I also took off the zip ties, which were a pain to get off too. They have to be so small to stay on and the chicks grow so fast.
So the 7 that are wing banded will be weighed still but I won't bother with the rest. I weighed them before putting more feed down so they didn't have huge crops full of food for weighing.
The colors are interesting. I think a couple are penciled black lines, like barring is. There is definitely alot going on in the background that will be popping up breeding from the FR. From the variations in mine and what I've seen in others pics, I'm thinking that for the parent/grandparents breeding they are only weeding out colors like too much dark or darker pin feathers. Not for any certain color or pattern. Just for heavy meat production and cutting off colors or patterns that don't work for light pins and more fiddly plucking. Which makes sense for that market.
