Flash is a Barred Rock pullet. Loki....I'm not really sure on breed, but not Barred Rock. The other 2 Barred Rocks you got are cockerels which is why they look different than flash. Here is a picture of my pair. The roosters always have more white on them.I got these as pullets from TSC about 2 months ago but I am unsure of what breed they are any help would be appreciated.
