Where did you get her? If from a breeder she might be a true Ameraucana but if from a hatchery she almost certainly is an EE. EE’s are not a breed, they are essentially a barnyard mutt that might lay a blue, green, pink, white, or brown egg of any shade. Since they are essentially mixed chickens they might start to lay early or late or they might lay seldom or often. Since they are not a breed they don’t have breed tendencies. Plus individuals in even purebred birds from the same flock can vary tremendously in when they start laying or how often they lay.
Hens do not need 12 hours of daylight to ovulate or 14 hours of daylight to lay eggs. I usually have hens laying an egg a day in the middle of December when the length of day is less than 10 hours. Length of day is not the determining factor. Length of day can have an influence in how often they lay for some hens, but that’s because their body used daylight to regulate when a yolk is released to form an egg so they don’t wind up needing to lay at night. The less daylight the less often they release a yolk.
Days getting longer or shorter has a lot more influence on when they start or if they continue. If you are in the northern hemisphere where the days are getting shorter that might have an influence on when she starts, but I’ve had EE pullets start laying in the middle of December, during the shortest days of the year and with the days getting marginally shorter. I’ve had EE’s start to lay at 18 weeks, I’ve had EE’s start to lay at 9 months.
To your basic question, is it possible for a hen to be barren? You are dealing with living animals so yes it is possible. You just don’t get guarantees on behavior with living animals. Is it likely, no, but it is possible. To me there are three main possibilities, each more likely than her being permanently barren. She may be hiding a nest, she may be laying an egg not blue or green, or she may just not have started yet.
