This morning I found one of my hens cannot raise her head, her neck was streched foward, or sometimes she twisted aside. She can stand or walk one step or two, but otherwise very weak. She has no interest in food or water. Her eyes are open and very clear. No discharge, no labored breathing. But her neck was completely limp. Yesterday in the day she was well, then in the evening she didn't fly up very high to go to sleep, as she was used to. Then this morning I found her in a very bad situation. I fed her water with electrolyte whole day. I don't think she has drunk much as she struggles, some water came out and sometimes she got choke. Now she can raise her head a little bit, but not for long. She's one of the free ranging hens, I suspect it's botulism as the day gets very hot and wet recently. She may have eaten something outside that contains the tocsin. I felt her crop, there seems to be nothing. She dropped some green poo. I didn't feel any eggs in her vagina, I don't think it's egg binding. So far all my other chickens seem to be fine. Does anyone has the experience with botulism?
