I am currently very concerned about the condition of my only adult hen. It is currently noon where I am, but she has not left the place where she lays her eggs a single time today. When I try to check on her, she shrieks at me; more noisily than what is usual. She has never stayed in her laying place for this long before, except when she went broody, which I doubt is the case here (she only started laying eggs again a few weeks ago). Could she be egg-bound?
