Why Won't My Chicken Leave the Nest Box? (Broodiness)
A hen glued to the nest, flattened like a pancake and growling when touched, is broody — hormones telling her to hatch eggs, whether or not any exist.
Most likely causes
Broodiness
What points to it: Flat 'pancake' posture over the eggs, growling/shrieking and pecking when you reach in, plucked breast feathers, one giant smelly dropping a day, brief frantic food runs, returning to the same box for days.
What to do: Decide fast: give her fertile eggs to hatch (she'll sit ~21 days), or break the broody spell — daily removals to a wire-bottom 'broody breaker' crate with food and water for 2-4 days usually resets the hormones. Half-measures (just tossing her off the nest) rarely work and prolong it.
Not broody — something else
What points to it: Hunched in the box but not defensive, eyes dull, not eating at all, or straining — that's a sick or egg-bound hen using the box to hide, not a broody one.
What to do: Pull her out and assess: broody hens are ferociously alert; sick hens are flat in a different way. See the lethargic and egg bound guides.
Check these first
The tell is attitude: reach toward her — a broody puffs, growls, and pecks. Check she's actually eating on her breaks (broodies lose condition fast), and confirm eggs under her aren't a rotting stash.
When it's probably nothing
Some breeds (Silkies, Cochins, Orpingtons) go broody constantly — it's genetics, not malfunction. A hen hogging the favorite box for an hour to lay is also normal; broodiness is measured in days, not minutes.
