I also thought the same thing until I posted a question in the breeds genetics and show thread. So I'm not trying to make you feel stupid at all. It was just two months ago that I thought the same thing.That's interesting, because that's what I thought, then someone on BYC vehemently said I was wrong, and I shrugged and went with it. I always thought that Production Red meant RIRs that are bred for egg production rather than type, and were what most hatcheries sold.
But since I got called out for saying so, I changed what I told people. I'd very much like to know which is right! In the mean time, I'll shut up over here.![]()
Production Reds are not sexable by colour at hatching. Boys are the same as girls in that factor. Red Sex Links are sexed by colour. The female is a sandy colour, and sometimes has stripes down the back. The males are yellow.
Here is the difference between male and female RSL.
Production reds are crossed, but do look closer to the RIR
