I had several chickens die suddenly about 6 months ago. All with the same symptoms. Lethargic, not walking or stumbling, death. All of my others have been fine, til lately. I have a 1 yr old hen that started acting lethargic. I separated her immediately not knowing again what was wrong. She became so week she couldn't hold her head up. I gave some vitamins and got some tylan 50 injections for her and the flock just in case. I would have bet anything she would have died that night but somehow she pulled threw. She is still sickly...I've been trying to give cheese, corn, yogurt...anything she will eat. Well today I noticed very bright green poop. I googled it and the first thing that popped up was botulism. I read some them remembered where the coop is built is an old vegi garden spot. It has rained here what seems like forever and puddles of standing water are everywhere. Has any one dealt with botulism? and is there anything I can do for her and the others until I am able to move the coop if it is bot.??
