The last shot appears to possibly show black feathering coming through in the tail - is that the case or just the way the picture looks?
ETA - you posted another picture while I was posting - this is in reference to picture in post 7
The bird front and center looks to be a production red - much to light to be a RIR, the bird in the background (at the waterer/feeder) is more likely to be a RIR.
