Broiler vaccination schedule: planning guide
A broiler programme is short and front-loaded. Most of it happens at the hatchery and in the first three weeks, because the birds are sold at around six weeks. The main decisions are which early vaccinations to repeat and whether local disease pressure justifies extra cover.

Before anything else
Vaccination programmes differ by country, hatchery, disease pressure in your area and the vaccines available locally. Treat the ages below as a planning framework and confirm your final programme with a qualified veterinarian or your county or district veterinary office before you buy vaccines.
Planning stages
| Stage | Age | What normally happens |
|---|---|---|
| Hatchery | Day 1 | Vaccinations given before delivery — request the written record |
| Early brooding | Week 1-2 | First on-farm vaccinations as advised locally |
| Mid cycle | Week 3 | Booster where your vet advises |
| Finishing | Week 4-6 | Normally no vaccination; focus on biosecurity, litter and ventilation |
Withdrawal periods matter
Any medicine given to birds destined for the table has a withdrawal period before slaughter. Record every treatment and respect the withdrawal stated on the product, both for food safety and for your reputation with buyers.
Safe things you can do today
- Request the hatchery vaccination record with every batch of chicks.
- Write the programme on the wall of the house on the day chicks arrive.
- Keep a treatment log with withdrawal dates for every batch sold.
Every farm is different — describe yours
KukuVet asks one short question at a time, then gives you a plan for your birds. Free to start, in English or Kiswahili.
Example: “I have 1,000 broiler chicks arriving on Friday. What should my programme look like?”
Common questions
Do I need to vaccinate broilers if the hatchery already did?
Often some repeats are still advised locally, but not always. Get the hatchery record and ask your vet rather than guessing in either direction.
