Thanks so much Chelsebell. I am contacting that link you shared. Also appreciate your taking the time to explain ringer's Lactate.
Her wound is actually looking amazing. I had to debride it Sunday and then go our of town for two days. Today (Tuesday) I checked it and it is granulating. She seems very healthy, but is hanging close to the coop. I feed her some yougurt in a nest box, to help with extra nutrition and to counteract the antibiotic poopers.
I wrap the wound in order to keep the other hens from pecking her. I started spraying Vetricyn (sp?) on it Sunday and am really amazed at the progress.
I am worried that she won't have enough feathers on the back of her neck now to prevent sunburn and chickens pecking at her, but will see what happens. If that is the case, I'll just have to treat her with some no peck medication for the rest of her life. I hope she grows enough feathers around the wound to cover it though.
I've had two injured chickens before, and neither survived. So I'm really happy she seems healthy so far.
