Lao Zhou, a farmer in Nanyang, Henan, keeps 8,000 layers. Every summer, his biggest headache isn’t the heat – it’s the smell.
“You can smell it 200 meters before you reach the coop. Neighbors cover their noses when they ride past on scooters. When I go in to collect eggs, myhttps://jbhtechy.com/?p=435 eyes water, and the chickens keep coughing.”
Lao Zhou tried lime, air fresheners, even cleaning twice a day – nothing worked. Finally, he switched to a new approach. Within three days, the ammonia smell in the coop dropped dramatically, and the neighbors stopped complaining.
This article shares the dead ends Lao Zhou hit and the methods that actually worked.
1. Why does chicken manure smell so much worse in summer?
Many farmers think, “It stinks because it’s hot.” Heat is only a catalyst. The real reason is: bacteria break down protein and uric acid in manure, releasing large amounts of ammonia and hydrogen sulfide.
In summer, high temperature and humidity cause bacteria to multiply 5–10 times faster than in winter. If ventilation is poor or manure removal is delayed beyond 24 hours, the odor multiplies.
Ammonia is not just smelly – it harms chickens:
· Irritates respiratory tract, leading to airsacculitis and E. coli
· Reduces egg production (can drop 10–20% in severe cases)
· Causes tearing, blindness, and reduced feed intake
Here’s the English version of the article about summer chicken manure odor.

Chicken coop stinks so bad in summer you can’t open your eyes? These 4 methods cut the smell by 80% in 3 days

2. Bad ideas Lao Zhou tried (and why they failed)
Method Result Why it failed
Flush manure trench with water every afternoon Water bill skyrocketed, smell got worse Water doesn’t stop fermentation; moisture encourages bacteria
Sprinkle quicklime Chickens coughed more, eyes became red Lime dust irritates respiratory tract; doesn’t absorb ammonia
Spray air freshener Perfume + manure = even worse Treats symptom, not cause; chemicals bad for chickens
Add more exhaust fans Smell blown to neighbors – complaints increased Only moves the odor, doesn’t eliminate it
Lao Zhou spent two months realizing: if you don’t change how you handle manure, any cover‑up is a waste of time.

3. Four methods that actually work (field‑tested)
1. Install a belt‑type automatic manure removal system, clean twice a day
Lao Zhou used a scraper system, cleaning once a day. But in summer, odor started within half a day. He switched to a belt‑type automatic manure removal system, set to run at 7 AM and 7 PM. Manure stays in the cage less than 12 hours – it’s removed before significant fermentation starts.
Result: Ammonia concentration dropped from 50 ppm to 8 ppm (almost unnoticeable).
Cost: About 20,000–30,000 RMB for 8,000 birds. The money saved on medicine plus extra eggs paid for the system within a year.
If you can’t afford the investment, at least clean twice a day – never leave manure overnight in summer.
2. Add probiotics or citric acid to drinking water
Lao Zhou’s vet recommended lactic acid bacteria probiotics (e.g., EM bacteria) at 500 ml per ton of water. Probiotics improve intestinal digestion, reducing undigested protein in manure – cutting ammonia at the source.
Alternative: citric acid – add 0.1%–0.2% to drinking water (1–2 kg per ton). Lowers manure pH and inhibits ammonia‑producing bacteria.
Result: After two weeks, manure was more formed, odor noticeably reduced, and eggshell quality improved.
3. Install a simple water‑curtain filter on exhaust fans
Lao Zhou added a simple misting system outside his exhaust fans – a row of small nozzles plus a corrugated paper pad. Exhaust air passes through the water curtain, which absorbs more than 70% of ammonia and hydrogen sulfide.
Cost: A few hundred RMB using DIY materials. Neighbors stopped complaining.
4. Sprinkle zeolite powder or bentonite on the floor
If you can’t modify equipment immediately, sprinkle zeolite powder (100–200 g per square meter). Zeolite is porous and absorbs ammonia like a sponge. It’s inexpensive (a few hundred RMB per ton).
Result: Lasts 3–5 days per application – low cost, good for small farms or temporary relief.

4. Lao Zhou’s coop now
One month after the changes:
· No more tears when entering the coop
· Chicken coughing significantly reduced
· Egg production recovered from 82% to 91%
· Neighbors stopped complaining – they even asked what he did
Lao Zhou did the math: automatic manure removal + probiotics + water curtain cost him less than 30,000 RMB. The savings on medicine, extra eggs, and fewer dead birds brought him an extra 50,000+ RMB per year.

5. Summary: Summer odor control – “fast, fundamental, auxiliary”
Step Core measure Effect
Emergency Increase cleaning frequency (twice/day) + sprinkle zeolite Immediate 50% odor reduction
Fundamental Belt‑type automatic manure removal + probiotics/citric acid in water 80% ammonia reduction
Auxiliary Water curtain on exhaust fans No neighbor complaints, eliminates external odor
If you’re struggling with summer manure odor, stop using lime and air fresheners. Start by increasing cleaning frequency and adding probiotics – a small investment can solve a big problem.
