I have 1 RIR and I believe she is the one that lays the soft egg, in spite of all the oyster shell or ff I feed them. When our fuel co came to change out our propane tank, his family raises RIR's and he said that they used to have these problems until they gave them chick grit. Didn't make a difference with mine. After changing out a nest and cleaning it almost every single day, I'm taking steps this week end to making sure it's her and then she's gone. I've done this for 2 years and enough. Have you ever found a breed that seems to lay soft egg shells? I bought her as a pullet from a farmer so I don't know of her origin. She gets free range anywhere she wants here.
