Went out to let her out Monday morning she was not on the perch with the rest of them was sitting on the floor of the coop. She went out with the rest of them but could not jump up on the perch that evening.soaked in vinegar and water had poop stuck to her bottom. She had a large raw spot under her tail,put bag balm on it.she has been pooping but not like she should be. Was eating and drinking but getting harder for her to move. This morning can't move anything but her head.
Botulism usually progresses fast within day or so. If it is that she needs to be hand fed or tube fed fluids and ground feed. Check the feed for mold or a bad odor which can cause illness. With Mareks disease, it can progress quickly in some cases, but in others the chick may eat and drink normally. I would send in her body to the state vet for a necropsy of she should die. The body should be refrigerated and shipped on ice or dry ice.
