Thank you for your email. Most of your question are answered in the statement below. Turkeys and Pheasants are grown and hatched in separate facilities from the chickens and are there for not affected.
If you have any additional question please contact us.
Avian Encephalomyelitis (AE) is passed from the infected hen (the only symptom being a drop in egg production) through the egg into the chick. Chicks from infected hens display AE symptoms within two to three weeks of age. Those chicks are infectious and should be quarantined until well after symptoms are no longer displayed. All equipment and housing should be disinfected and litter disposed of properly. Surviving chicks will be immune to AE in the future, will not shed the virus, and will pass this immunity on to their offspring.
In February one of our larger breeder flocks had a well water quality problem. We took corrective action and treated the well water. There was also a reduction in egg production as well as poor hatchability at that time. We falsely diagnosed the egg production problem as being water related. A few weeks ago we had reports of mortality in some birds and recently we have had a confirmed report of AE, for which our flocks had been vaccinated. As you can imagine this left us in a quandary as to how this could have happened.
By consulting with veterinarians we confirmed that AE runs it course in adult birds for 1 to 2 weeks and the surviving birds are immune. That period of time has elapsed; *eggs and chicks from our now immune breeding flocks will not be infected.*
We are sorry for any inconvenience and problems caused and thank you so very much for your patience and understanding of this most trying time for McMurray Hatchery. Just as we done for the last 90 years you can again expect the same high quality chicks in all future orders.
