What is it?

A broody hen is a laying hen whose hormones have switched her from egg production mode to incubation mode. She refuses to leave the nest box, fluffs up and clucks aggressively when disturbed, stops laying new eggs, and may sit on empty boxes or other hens' eggs. Breeds like Silkies, Buff Orpingtons, and Brahmas go broody often; production breeds like Leghorns and Rhode Island Reds rarely do.

What are the symptoms?

• Hen sits in the nest box all day and all night, even without eggs
• Refuses to leave the nest except briefly (once or twice a day) to eat, drink, and defecate
• Fluffs up and clucks/growls when you approach the nest
• May peck your hand when you reach under her
• Pulls out her own breast feathers to line the nest
• Stops laying new eggs
• Body temperature rises (broody hens feel hot to the touch)
• Loses weight from skipping meals

What causes it?

• Hormonal trigger from increased daylight (spring and summer), seeing accumulated eggs in the nest, or genetics (some breeds are simply broody-prone)
• Empty or shared nest boxes — if a hen sits alone in a quiet nest, broodiness often kicks in
• Older hens tend to go broody more than first-year pullets
• Warm weather intensifies broodiness in predisposed breeds

How to treat it — step by step

1. Method 1: Cool the keel. Place the hen in a wire-bottom dog crate or rabbit cage with food and water but no bedding or nesting material. The cool air circulating under her belly drops her body temperature and resets her hormones. Most hens break within 2-3 days. This is the kindest and most reliable method.
2. Method 2: Daily removal. Lift the hen off the nest box every time you see her sitting (10-20 times a day). Tedious but works for mild cases over 5-7 days.
3. Method 3: Block the nest box. Close off or remove the nest box she favors for 5-7 days. She may switch to another nest, but interrupting the routine often breaks broodiness.
4. Method 4: Cold water dunk (older school). Some keepers dunk the hen's belly in cool water once or twice. Effective but stressful — not recommended unless other methods have failed and you have experience handling chickens.
5. Always ensure the hen has food and water she actually uses during treatment. Some broody hens stop eating even when food is available; you may need to gently encourage her with treats.

How to prevent it

• Collect eggs at least once daily — empty nests reduce broody triggers
• Provide enough nest boxes for the flock (1 per 3 hens) so no hen has an empty private nest for hours
• Use ceramic 'fake eggs' sparingly — they encourage laying in the right place but can also trigger broodiness
• For breeds known to go broody (Silkies, Buff Orpingtons, Brahmas), accept that they will go broody 2-3 times per year and plan accordingly — either let them sit and hatch eggs, or break them early before they lose too much weight
• Keep the coop ventilated — hot stuffy nest boxes encourage broody hormones

When to call a vet

• Hen has lost more than 20% of her body weight while broody
• She is severely dehydrated (sunken eyes, pale comb, weak legs)
• She has a wound on her breast from sitting too long
• Broody behavior persists beyond 21 days of intervention
• Other signs of illness (lash egg, discharge, lethargy) appear
