Ok, so after endless hours of researching and reading till my eyes are crossed and my head is mushy, now I am 99% certain my favorite pet rooster (and probably the other 3 chickens I lost) has botulism. They all had similar symptoms - droopy, weak legs (never the Marek's split), very red face, lethargic (but eating well) - but it was the sudden loss of his neck feathers and others coming out easily finally made it all come together. None of the other symptoms added up completely to Marek's or FC and I have had 2 other chickens completely recover after long periods of hospital care. All the chickens got sick during really rainy, humid periods and were out in the run. All the house chickens and chickens living in the garage are perfectly healthy. I have seen watery green poo in some of the girls outside but thought it was just from the greens/grapes. Now I know better. They are larger and older and probably were able to handle the toxin better. These were little OEGBs and a young Silkie (she has recovered and I'm not exactly sure that hers wasn't an injury because it was so different). The weird part is that only my Barred OEGBs have died or been effected? We have had so much rain this year and the combination of mud puddles, scratch, mice and who knows what else staying in the soil has triggered this outbreak I am sure. I feel absolutely awful that I have killed/sickened my babies, but now that I know, I can treat and deal with it and try to never make the same mistakes again. I have all the information about the flushes I need to do and the follow up treatments for the birds but what do I do about the soil? There is no possible way I can close it off to my flock. I just can't. It is their run and the only place I have for them. Moving them is not an option and I can't keep them locked in the coop. Should I turn it over? Should I add something to it? Should cover it thickly with wood chips/shaving/etc? Will the sun and heat we now have on the way help? Any quick help and advice would be appreciated. **I edited this to say that I am positive it is botulism now. I have been flushing him out with epsom salt mix and the nasty junk coming out is exactly what they describe on other sites. He is following the symptoms down to a tee. This is both good and bad I guess - at least I know what I'm dealing with this time. His crop and waddles are so red and he is hot to the touch. I am not being cruel to him but I did test his feathers and they come out without any effort at all I am just heartbroken but determined to do everything I can to treat him and clean up this problem in the run, which is the help I am looking for. Since my first post, the other sick OEGB pullet died so I rushed her to the lab for a necropsy. Hopefully I will have the results back soon and it doesn't show I'm dealing with another problem too! **edited again to say he died so now I wait and see what the results are. I guess when I find out, I will figure out what I need to do.
