HI, I'm confused a bit. I ordered RIR pullets from the feed store. From the start, one was a dark red while the rest were yellow-tan with red markings on the backs of the wings, except one who had a tan stripe down her back. As they started to feather out, the dark red one stayed dark red, but acquired lovely bars on the ends of her wing feathers. The rest of the flock became cream colored, or tan, or cream with red, or tan with red, or just red. Since I expected RIR chicks to turn red, I posted to the "What breed or gender" topic to ask why my RIRs were not R. I was told that the dark one with barred wings was probably a "production red", and that the rest were probably sex-links. I did some research and read that this is done to keep the production levels high. My question is, why would birds be sold as RIR, actually be mixed breeds? And how do I know what I'm getting the next time I order? And what is a production red - how is it different from a plain RIR? Mind you, I just want eggs, so I don't really care what color the hens are. They are lovely, by the way, and it's nice that I might be able to tell them apart! Thanks for any education you can give me!
