I thought she had a chance, but that has changed. Spoilered for those who don't want to read about the full extent of the injury,
My husband offered to gently clean the wound while I was taking care of the other birds. He did, then we covered it in Blu Kote. He took her over to put her in the isolation bin with her egg and shock water. A few seconds later he came over and just told me "you need to end it, please just kill her." I don't know if I somehow missed it last night (I don't think so, because she did consume a bit in front of me) or she was worrying at the wound and made it worse, but when she would take a drink or gobble down some egg, it would fall down from under an intact-looking bit of skin and dribble down her wound. Her trachea was severed at least partially above the skinned area, right beneath some remaining skin. How she is breathing without any distress is beyond me.The injury is just more than I feel I can be repaired by me or the local 'farm' vet and still give her a good quality of life.
I'm getting the kids settled in and distracted and then I am going to cull her,
Thank you for being willing to put her out of pain.
