I have an Easter Egger who's not quite a year old. She was my first layer and was very regular for a few months, then she just stopped a few months ago. She isn't broody, she doesn't seem to be moulting (spring seems like an odd time for that anyway). She doesn't seem to be in any discomfort, nor does she seem to be over weight. She happily runs around with the other hens, and has free access to layer pellets. She just hasn't laid eggs for a few months.
