The recommended dosage of Corid 9.6% for chickens is typically 1.5 oz per gallon of water for 5-7 days to treat coccidiosis.
Coccidiosis is a common and dangerous poultry disease caused by protozoan parasites. Using Corid 9.6% solution correctly can save your flock. This guide covers exact dosages, treatment protocols, and expert tips for effective coccidiosis management.
Understanding Corid 9.6% for Chickens
Corid 9.6% contains amprolium, which works by mimicking thiamine (Vitamin B1). This starves the coccidia parasites since they require thiamine to survive. The medication comes in liquid form for easy water administration.
Key Facts About Corid 9.6%
- FDA-approved for laying hens (no egg withdrawal required)
- 24-hour meat withdrawal period before slaughter
- Effective against all major Eimeria species affecting poultry
- Works best when given as sole water source during treatment
Exact Corid 9.6% Dosages for Chickens
| Situation | Dosage | Duration |
|---|---|---|
| Severe outbreak | 2 tsp per gallon | 5-7 days |
| Moderate outbreak | 1 tsp per gallon | 5 days |
| Prevention | ½ tsp per gallon | 21 days |
Important Treatment Notes
- Always treat the entire flock – coccidia spreads quickly
- Change medicated water daily for maximum effectiveness
- Do not give vitamins during treatment (they counteract Corid)
- Follow severe treatment with ½ tsp/gal for 7 more days
Recognizing Coccidiosis Symptoms
Early detection improves treatment success. Watch for these signs:
Common Symptoms
- Bloody or watery droppings
- Pale combs and wattles
- Lethargy and huddling
- Reduced appetite
- Weight loss despite eating
Young chicks (2-8 weeks) are most vulnerable. Older birds can carry coccidia without symptoms but spread it to others. If you notice sudden chicken deaths, coccidiosis should be suspected.
Advanced Treatment Protocol
For best results, follow this comprehensive approach:
- Confirm diagnosis (fecal test if possible)
- Remove all unmedicated water sources
- Mix Corid at appropriate strength
- Treat for recommended duration
- Follow with vitamin supplementation
- Clean and disinfect coop thoroughly
Post-Treatment Care
After Corid treatment, provide vitamin supplements for 3-4 days to help recovery. Good options include:
- Rooster Booster Poultry Cell
- Nutri-Drench
- Electrolyte solutions
Preventing Future Outbreaks
Coccidiosis thrives in wet, dirty conditions. Reduce risk with these measures:
Housing Management
- Keep bedding dry and clean
- Provide adequate space (overcrowding spreads disease)
- Use proper coop sizing for your flock
- Implement good ventilation
Natural Preventatives
- Apple cider vinegar (1 tbsp per gallon occasionally)
- Garlic in water or feed
- Probiotics to support gut health
- Diatomaceous earth in dust baths
When to Consult a Veterinarian
Seek professional help if:
- Symptoms persist after treatment
- Multiple birds die suddenly
- You need confirmation of diagnosis
- Your flock has recurring outbreaks
