I just bought 7 RIR chicks, and I want to double check and make sure thats what they are. If you can tell from looking, can you verify that these are RIR chicks? There was also someone there selling NHR chicks, but they looked different than these. I am hoping that I am right and they are all RIR! Let me know if you need a closer shot. Also, can someone take a stab at their age? I guess 3 weeks.
