I have these, they were marked as cornish cross straight run at my TSC. I definitely have a roo and two hens. The hens now look like red sex link hens and the roo is all red with green tail feathers growing and green tips on his wings that are now growing which is unlike all the cornish rock crosses I see pictures of here. He also has small black dots on his "cape" on the neck. The hens and the roo have small, long pointy feathers on their "cape" (neck). So what do I have. They also grew faster than my other BR hens and are bigger but not by much. I will try to remember updated pics on Monday. But what chicken is red and grows green tail feathers? Thanks. Edited it to include "Grown Up" pictures in post #9.
