🐣 Broodiness: Hormonal Changes & Management Considerations

Is your hen refusing to leave the nest, puffing up, and growling at you? She's gone broody! Let's understand the science behind this behavior.

What IS Broodiness? A hormonally-driven state where hens stop laying and focus entirely on incubating eggs—whether fertile or not!

The Hormonal Shift:

PROLACTIN (The "Broody Hormone")

⚡️Surges when broodiness begins

⚡️Suppresses reproductive hormones

⚡️Stops ovulation (no new eggs!)

⚡️Triggers nesting, protective behaviors

⚡️Causes breast feather loss (bare "brood patch" for heat transfer)

ESTROGEN & PROGESTERONE

📉Decrease during broodiness

📉Redirects energy from egg production to incubation

Physical & Behavioral Signs:

🪺Refuses to leave nest (day AND night)

🪺Puffs up, growls, pecks when disturbed

🪺Pulls breast feathers for nest lining

🪺Pale, shrunken comb (reduced hormones)

🪺Large, infrequent, smelly droppings

🪺Stops laying completely

Breed Tendencies:

🐔HIGHLY BROODY: Silkies, Cochins, Orpingtons, Brahmas, Australorps

🐓RARELY BROODY: Leghorns, Production Reds, most commercial hybrids (bred out of them!)

Management Options:

IF YOU WANT CHICKS:

✓ Provide safe, quiet nesting area

✓ Give 10-12 fertile eggs

✓ Ensure food/water nearby

✓ Incubation takes 21 days

IF YOU DON'T WANT BROODINESS:

"Breaking" a Broody:

🐔Remove from nest repeatedly

🐔Place in wire-bottomed cage (cools underside)

🐔Ensure bright lighting, no nesting materials

🐔Takes 3-7 days typically

Why Break Broodiness?

🐓Hens don't eat/drink properly

🐓Weight loss, weakened condition

🐓Won't return to laying until broken

🐓Can last weeks or months!

Health Concerns:

💦Dehydration (may only leave nest once daily)

🕷️Parasite buildup from constant sitting

💧Nutritional deficiency

🐾Vulnerable to predators while "zoned out"

Your turn:

❓Do you let broody hens hatch eggs or break the broodiness? Why? 🥚
