Hi, I have a RIR that is 24 weeks. She looks to be heritage,but she has more of a narrow tail. Maybe she isn't mature yet in that way, but she is almost ready to lay and I thought heritage breeds are late bloomers. I can fit about 3 fingers between her pelvic and 4 between her keel. Hasn't laid yet. Here are some pics She is a deep red. I forgot to mention that I got her from a private breeder.
