Hello, I have a 1.5 year old black sex link hen, who became extremely lethargic, anorexic with a massive amount of weight loss. She also I found her over a week ago on the sprawled underneath the perch in her coop, as if she had fallen, as she was falling asleep. The other hens were fine and were sleeping already on their perch. When I picked her up off the dirt ground, she was almost lifeless, and I thought she was dead, up until she moved slightly. I brought her in the house, warmed her up, and syringe fed her. She made it through the night, shockingly. The next few days, I noticed she couldn't even walk. I purchased Emerald Omnivoire food (a semi-elemental diet designed for the critically ill omnivore; http://emeraid.com/emeraid-omnivore/). I syringe fed her this diet three times daily, then reduced it to only twice daily (only because I was running the wrong house and each bag is $65). I mix in Apple Cider Vinegar, Colloidal Silver, and more electrolytes for chickens). I also give her pedialyte by syringe. It has been over a week, and she just barely started eating today a little bit of corn on her own. Her keel bone sticks out and you can feel her ribs. Her comb has some weird scabs in it, that recently have turned whitish (see pic), and green watery diarrhea.. A few days ago, she started walking "kinda," (lopsided), then past three days, her walking has further improved, but still obviously noticeably weak. I'm a physician assistant, and have tried putting differential diagnoses together based on everything that I've read on here. Fowl pox (based on her comb, or a fungus?), Marek's (lopsided walk), cocci (diarrhea)... I don't think she's egg bound, because she would have been dead awhile ago. she's not sneezing, or coughing, nor does she breathe when her mouth is open. Help!
