DOES THE METHOD OF VACCINATION AFFECT THE AGE WHEN CHICKS CAN BE VACCINATED WITH COCCIVAC?
A. Yes. When the Spraycox spray cabinet is used, chicks can be vaccinated in the hatchery because the sprayer enables uniform distribution; 21 ml of coarse spray is delivered for each box of 100 chicks. Chicks preen to clean and dry their feathers and ingest the vaccine. Red dye mixed in with the vaccine gets their attention and stimulates preening. An alternative to using the Spraycox applicator is feed spray application. It does not deliver the vaccine as uniformly as the Spraycox applicator, but can be used when hatchery application is not possible. Chicks must be 4 days of age, however, since younger chicks may not have developed uniform feed consumption patterns. Q.
