They are straight run. I can now tell that they are different ages because of the difference in the developement. I belei e that a few are about a week behind. Thwy were probably the new shipment and the othera were from the previous the week before. The younger ones are starting to darken...
I bought what was supposed to be Isa Browns about a week ago from TSC. They just don't look dark enough to me. One is dark, but the rest are the light yellow color. This is my first go around as an adult raising chicks.
