Hen on strike??

My hen (starlight green egger) has not laid eggs for a year. I got her as a chick last Feb and she started laying last year, then I let the hens take the winter production off and she has not started laying again.

My other hens have started up production again as usual (except for my broody maran 🙄)

Also I swear I heard her trying to crow.

Has anyone else had a hen that just stopped laying? Can I do anything to get her laying again?
