New chickens should be quarantined for at least 30 days to monitor for diseases and ensure they are healthy before introducing them to your flock.
Bringing new chickens into your flock requires careful quarantine to protect your existing birds. The standard quarantine period ranges from 2-4 weeks, though some poultry keepers extend this to 6 weeks or longer for maximum safety.
Why Quarantine New Chickens?
Quarantine serves three critical purposes:
- Prevents disease transmission
- Allows observation for hidden health issues
- Gives time to treat parasites before introduction
According to Backyard Chickens, many poultry diseases have incubation periods of 2-3 weeks. A proper quarantine lets symptoms appear before exposing your flock.
Recommended Quarantine Duration
Minimum Quarantine Period
Most experts recommend at least 30 days. This covers:
| Disease | Incubation Period |
|---|---|
| Marek’s Disease | 2-4 weeks |
| Respiratory Infections | 1-3 weeks |
| External Parasites | Visible within days |
Extended Quarantine Options
Some keepers prefer longer quarantines:
- 45 days for added safety
- 60-90 days for high-value flocks
Quarantine Setup Requirements
Location
Your quarantine area should be:
- At least 30 feet from main coop
- Completely separate air space
- Easy to disinfect
Equipment
You’ll need dedicated supplies:
- Separate feeders/waterers
- Disposable bedding
- Cleaning tools
Quarantine Health Checks
Daily Observations
Monitor these signs closely:
- Appetite and water consumption
- Droppings consistency
- Respiratory sounds
Parasite Control
Standard treatments include:
- Dusting for mites/lice
- Deworming medication
- Foot baths for scaly leg mites
Introducing Quarantined Chickens
After quarantine, introduce new birds gradually. The introduction process typically takes 1-2 weeks.
Visual Introduction
Start with 3-7 days of:
- Separate but adjacent enclosures
- Shared visual access
- No physical contact
Supervised Free Range
Next phase includes:
- Short, supervised outings together
- Multiple feeding stations
- Plenty of escape routes
Special Considerations
Egg Safety
Don’t consume eggs from quarantined hens for:
- 45 days if medicating
- 30 days minimum otherwise
High-Risk Sources
Extend quarantine for birds from:
- Auctions or swaps
- Unknown origins
- Commercial operations

When to Skip Quarantine
The only safe exceptions are:
- Day-old chicks from reputable hatcheries
- Your own birds returning from shows (still monitor)
Remember, as noted by Penn State Extension, “An ounce of prevention is worth a pound of cure” when it comes to poultry health.
