Repopulating after hot mareks??

I agree I definitely would vaccinate any chicks. I guess because the strain my last flock had was so devastating.

Did you have lab tests done to ID strain...so you can find the correct vaccination?

Wow - I didn't realize that there were strains different enough to require a special vaccine! Thanks - DOUBLE thanks - for the education!

I believe there are different vaccines....but not positive.
There are different strains and any vaccine is not always effective.

I have dealt with a "cold Mareks" strain and chickens that were not vaccinated. Effected birds are culled with resistant birds carried forward to replace losses. Last case I had was about 5 years ago even when flock have been kept continuously. The reservoir for the disease I think is migratory birds owing to seasonality of outbreaks (early fall) and some wild birds succumbing at same time to a condition that looks very much like Mareks. Local animal health experts do not report seeing same. The experts here are very much over paid.

Can someone please explain the difference between "hot" and "cold" Marek's?

Hot kills them faster.
Basically.

But is it a different strain....or an active vs inactive(dormant) status.

Who knows. I haven't researched it enough just yet.
It's on my list.

Maybe @centrarchid or @Sseckel can provide the answer?
