I have three 8 month old hens.  One started laying at 5 months is an Olive Egger and still laying, one is a Buff Brahma, squatting and looks like getting ready to lay, the other is a white Easter Egger and no sign of laying.  They aren't molting, either and it's early December.  Should I be concerned?
