I have an EE that I purchased back in March who hasn't started to lay yet. It's definitely a hen (no sickles or saddle feathers, rounded neck feathers) she has a total of 14 hrs a daylight / heat light, eats layer pellets with occasional left overs, is not molting, is at bottom of pecking order of 6 hens, no lice, no mites, not overweight, comb is red, pelvic bone is tight as can be. I've hatched and raised chickens for years, and this is a first for me. What am I missing?
