Lethargic for a week, and then death.

Both of these were home hatched. However...our first chickens, one of which is still around, came from an auction....I'm guessing she's a carrier. At this point though, we either deal with it, or cull 60+ chickens and start over. That's not likely to happen.

I wouldn't even consider culling, but that's just me... Having a necropsy done is probably your best bet. If it's too much trouble, do one yourself. Some I do, some I send to the lab, just depends on how lazy I'm feeling, lol.

Pictures of my last necropsy are here:
