My 24 week old Brown Leghorn has only a small pale ribbon like comb and no waddle. She shows no sign of laying eggs yet. Ruthie is one of 6 hens in my flock and the only Leghorn. The others (RIR, BO, SLW and Sapphire Blue) are all laying. She is on the bottom of the pecking order but she is getting sufficient food and water. I know they all will lay when they are ready but don’t know if there is something wrong with her. Any thoughts?
