Sneezing
Watery eyes
Reduced feed intake
Head shaking

๐ Facial swelling with foul smell
That smell is very common with Coryza.
Mortality
Usually lower mortality
But growth drops badly
Common Cause
Poor ventilation
Dirty environment
Stress
๐ฎโ๐จ 2. CRD (Chronic Respiratory Disease)
Usually linked with Mycoplasma infection.
Main Symptoms
Coughing
Sneezing
Rattling sound while breathing
Stretching neck to breathe
Foamy eyes sometimes

๐ฉ 3. โSamolina Diseaseโ
(Farmers often use this name for severe intestinal infection/coccidiosis-like diarrhea)

Overcrowding
๐จ IMPORTANT NOTE
Many farms have:
CRD + Coryza together
OR
CRD + Newcastle together
So always observe:
breathing,
swelling,
smell,
droppings,
and mortality pattern together.
๐ ๏ธ FIRST EMERGENCY ACTION
If you notice symptoms early:
Separate weak birds immediately
This reduces spread.
Improve ventilation fast
Especially for CRD/Coryza.
Change wet litter
Very important for diarrhea diseases.
Give electrolytes + vitamins
CRD
Anti-mycoplasma drugs commonly used
Improve ventilation urgently
Samolina/Coccidiosis-like disease
Anticoccidial drugs
Dry litter management
Clean water
