But this chick isn't dark.... With down it looks yellow with bits of brown at the tail and head. As it feathers those look like slate type coloring on the wings and back with a tinted yellow head (not dark brown or black with stripes) and the poster said some other light brown. I vote silver...
You sure the difference in shade isn't other genes? There can be silver red breasted, cinnamon red breasted, etc... My plain red breasted hen was dark just like the male red breasted. I saw no difference between them until they fully feathered. My lighter female that I have been told is red...
I think it looks a little light for a normal red breasted but it's hard to tell in pics.

It's really hard to tell when they are half feathered. You can tell the chicks by the down color, sometimes easier than when they are grown, and you can tell the adults when fully feathered but sometimes they go through some odd looking patterns while growing out. Both hatches now I've figured...
