So I have one coop on my farm that is a mix of breeds and I have had 7 die off. I did take a few to a local lab for necropsy. The results came back as them them having M.S. and one having Listeria. I have raised chickens for years and never had sickness before. Any advise on what to do with the ones I have left?

MS is a chronic respiratory and joint disease from mycoplasma synoviae. It is contagious and causes swollen leg and ankle joints, and pain. The respiratory symptoms may be milder than mycoplasma gallisepticum or MG. It is hard to treat or irradicate from your flock, since survivors may be carriers. Lysteria is something I know we can get from uncooked weiners, but I don’t know anything about the type that chickens get. In Merck Vet Manual, they say it can affect the heart, spleen, kidneys, and brain. We can get it from eating uncooked poultry. Here is the article to read:

I would probably wait to add or hatch new chickens to the flock until after all of these affected chickens are gone, waiting several weeks to get healthy baby chicks from a hatchery. That is the best way to handle common contagious diseases in flocks, so the disease does not get passed on.

Thank you very much much for the info, is there any prophylactic treatment I can give them to ward off anymore deaths?? Penicillin in their water? They go from healthy to can't walk within hours then dead in 12.

Lysteria will respond to certain common antibiotics, but you don’t want to be using an ongoing antibiotic with chickens, or you will not be able to eat their eggs. With most antibiotics, you would throw away eggs for 2-3 weeks after treatment ends. Only a few antibiotics may be obtained online without a vet, so a vet would be your best source. MS is very hard to treat and cure with antibiotics. Here is some info about MS:
