- For vaccination in water, starve the birds of water for at least 2 to 3 hours before giving the water containing the vaccine, so that almost all the birds will be thirsty enough to drink water.
- Add provided milk (tablespoonful) or liquid milk (4-5 tablespoonfuls per 7 liters of water).
- Provide enough water with a vaccine to allow birds to continue to drink the water for a maximum period of 30 minutes, but not less than 15 minutes.
