What is the recommended quarantine period for new birds to protect an established flock from IC?

Answer

Three to four weeks

Rigorous quarantine procedures are essential biosecurity steps to prevent introducing Infectious Coryza into a healthy flock. The established guideline for newly acquired birds is to house them completely separate from the existing population for a minimum period of three to four weeks. While the typical incubation period for IC symptoms to manifest is quite short (1-3 days after exposure), extending the observation window accounts for variations in incubation time, potential subclinical infections where shedding occurs without obvious illness, or exposure that may have occurred just prior to purchase. This extended monitoring period drastically reduces the chance of bringing an active or latent carrier into the main environment.
