🪶 Molting Science: Why Chickens Lose Feathers & What They Need

Is your chicken looking like she lost a fight with a pillow? She's probably molting - a completely normal (but dramatic!) process!

What IS Molting? The natural shedding and replacement of feathers, typically once a year. It's essential for maintaining healthy, functional plumage.

When Does It Happen?

🪶Usually late summer/fall as daylight decreases

🪶Triggered by decreasing photoperiod (day length)

🪶First molt around 16-18 months old

🪶Takes 8-16 weeks to complete (varies by bird!)

The Molting Process:

Head → neck → body → wings → tail

follows a predictable pattern!

🐓Some birds are "hard molters" (fast, dramatic)

🐔Others are "soft molters" (gradual, barely noticeable)

Why Egg Production STOPS:

Feather production requires MASSIVE protein and energy! Research shows growing new feathers takes priority over egg production - hens literally can't do both simultaneously.

Critical Nutritional Needs:

💪 PROTEIN is key! Feathers are 80-85% protein

🐤Increase protein to 18-20% during molt (vs. 16% layer feed)

🪱Offer high-protein treats: mealworms, black oil sunflower seeds, scrambled eggs

🐤Ensure adequate methionine and cysteine (sulfur-containing amino acids)

Normal vs. Concerning:

😊 Symmetrical feather loss following head-to-tail pattern

😊 New pin feathers emerging

🤒 Bald patches with no regrowth

🤒 Feather pecking by flock mates

🤒 Year-round feather loss
