We have had a run of bad luck lately. A fox has been killing off my flock. He killed my rooster and three hens two weeks ago but didn't make off with them. He came back yesterday, when I thought he'd moved on, to kill one of my geese and take off with a hen and a duck. Now I have one chicken left, who btw the fox dropped as he was leaving, as far as I can tell. She was lying in the snow as if she were dead and there were tracks leading away from her. She was bleeding from her beak when I picked her up and in shock but seemed to be moving and clucking in my tub later with no sign of blood so I put in the coup for the night. Now my ducks and the other goose really don't like her, they never liked the chickens so when I found her roosting by herself this morning away from them I wasn't surprised. But I did notice clear mucus dripping from her beak and she refused to eat or drink and then later in the afternoon I found she hadn't moved and then she still wouldn't drink when I set her beside the water, which was fun since she had a death grip on the roost. That's when I brought her in. Doesn't seem like a crop issue as far as I can tell but she tends to gasp for air here and there with the mucus filling her beak. I'm not thinking it's a broken rib at this time. She's acts sick or depressed and is pooping a white and yellow liquid with green wormy looking strands which I've read on here is a sign of starvation. She did lay an egg in the tub so she's not egg bound. I have kept her inside and cleaned the tub when she does poop, which has only been about three times today, so she's not sitting in filth. I've kept a bowl of water and some feed with her, she hasn't touched it but I have tube fed her a watered down concoction of brewers yeast, apple cider vinegar, lemon juice, ginger root, turmeric and black pepper. (Left over from when we were sick.) My first thought as to what was wrong, after depression, was thrush (yeast infection), which is why I figured a big dose of natural probiotics and chose to give her our cold medicine (which I make) and add the yeast, but I don't know as much about chickens as I do about ducks other then they get sick easily. We are talking to her and I held her until she got antsy so she's not lonely but other then eating up the petting she doesn't seem to care. If I can get her to eat I'd consider putting her in a diaper and letting her walk around the house a little bit but I think right now the tub is the best way to watch the poop. So now that I've bored you with the details the question is what might be wrong and what do I do? Is there anything I'm doing that could be hurting her more? Is this a stress thing or could it be depression? I know the fox broke the necks of all his kills could she be suffering from some kind complication from a fracture? I know that last one would likely require a vet but I figured I'd through it there. Thank You for taking the time to help me.
