The grey one was a free bird from Murray McMurray hatchery. I also think its probably a roo. Its 3 weeks old and barely any wing and tail feathers. He has feathered legs. Don't think he is a bantam as he is as big as my other 3 weekers. The yellow/white one came from TSC. We bought some Cornish rocks that were on clearance because they were 2 weeks already. Well they stick this one in there. Not sure the breed on it. This one too has feathered legs. I think it is a pullet.
