My hen was attcked by a dog on thursday. She is eating and drinking, on injectable antibiotics, wound washed with vetrimyacin and chlorahexa-something repeatedly. Was advised to put clay bandage on her (redmond clay) to suck out toxins and keep out other things. But, when i washed the clay it away today to change it, i saw that she has greenish discoloration in two areas. I was never able to flush tooth punctures as they were scabbed and closed by time i found her that night. I am not sure i did enough for her, honestly. She is eating and drinking. Not overly lethargic. Wound does not smell. Smells like dinner (raw chicken). What to do? Suggestions? Will this cut heal and grow feathers? Is this gangrene? Where to go from here?
