Okay, first off is a pic of some rosetta and dark tibetan tuxedo chicks. The rosettas are easy to tell at this age, they are the 2 that have a more reddish tint.
Next up is a pic of 2 red and 2 cinnamon as youngsters. There are some chukar in there as well, hopefully you can tell them apart!
In this one, the red is in the front, and another in the very back. The cinnamons are kind of hidden, but one is right in front of the red in the back, and the other is behind the red in the front.
In this pic, again the reds are in the front and in the back. One of the cinnamons is standing in front of the red in the back. Cinnamons are marked just like browns, but their coloring is very red.
This pic has the 2 reds on the right, and the 2 cinnamons on the left.
Better pic of the reds
This pic has the 2 reds in the center, one cinnamon under the light on the right, and the other is in the middle in the back.
And just because I'm bored, this is a pic of a dark tibetan
And this is a rosetta
There is also one called a golden range. I'm not sure how to tell the difference between that and a rosetta, they are very similar. I think my girl in the last pic is a golden range, rather than a regular rosetta, but I can't be sure.
