You are very smart to send yours for a necropsy. Always better to know earlier. Except for a whole hatch of chicks, my Marek's chickens have died one every few months or sometimes I'll go 6 months with no deaths. Most of my chickens that have gotten it have wasted away. In the end it seems they can't aim at the food. Paralysis is usually in younger birds. Usually. Please post the report when you get it.
I hope its not Marek's.
Just got an email that the histology is complete. It reads:
"HISTOLOGY FINDINGS:
Sections of trachea, lung, heart, liver, kidney, spleen, bursa of Fabricius, proventriculus, gizzard, intestine, pancreas, skeletal muscle, peripheral nerve have been examined histologically. Changes are in:
PERIPHERAL NERVE: There is multifocal, moderate infiltration of lymphocytes between the axons.
SPLEEN: Part of the normal architecture has been replace with a sheet of lymphocytes and lymphoblasts.
GIZZARD: There is severe infiltration of lymphocytes in the nerves and around blood vessels on the serosal surface.
HISTOLOGIC DIAGNOSES: Marek’s disease
COMMENTS: Histology confirms the initial suspicion of Mareks disease (primarily involving the nerves)."
So this is certainly a game changer. No more feed store chicks and the double stack brooders that I built into the hen house are useless now. Well, I guess not useless...I can still use the bottom brooder if I need to seperate an injured bird. Wish I had known before building it though. Not sure at this point how I'll go about chicks. How long do you keep your chicks seperate to allow adequate time for them to build resistance from the Marek's vaccination?
