UPDATE: Willow passed in the night. I'm sending her to UC Davis for a necropsy. 1) What type of bird , age and weight. Light Brown Leghorn, 1 1/2, 3 1/2 pounds 2) What is the behavior, exactly. Lethargy, darkened floppy comb, walking like she's "pregnant", poopy vent. 3) How long has the bird been exhibiting symptoms? Started looking "off" yesterday. But she was on the roost with the others last night. She walked (instead of running like the others) to get some mealie worms as a treat today - that's how I knew something was wrong. 4) Are other birds exhibiting the same symptoms? No. 5) Is there any bleeding, injury, broken bones or other sign of trauma. No. 6) What happened, if anything that you know of, that may have caused the situation. No idea. 7) What has the bird been eating and drinking, if at all. water, grower crumbles (we have youngsters, so they're all on grower crumbles), oyster shell, they got kale from the garden and yogurt as treats yesterday. Mealie worms treat today. 8) How does the poop look? Normal? Bloody? Runny? etc. Normalish. Not bloody. 9) What has been the treatment you have administered so far? Took her to the vet. The vet gave her subcutaneous water and x-rayed her for eggbound. Says it's probably a virus or bacteria. Gave us Baytril (antibiotic) and Metacam (pain reliever cuz Willow seemed to be "straining") 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? Just wondering if any folks here have any other suggestions as to what to watch for. 11) If you have a picture of the wound or condition, please post it. It may help. NA 12) Describe the housing/bedding in use Wood chips in the coop and run. They freerange during the day. I have her quarantined now. I hope it's nothing communicable. The other guess from the vet was possibly an internally laid un-shelled egg giving her peritonitis. Willow was one of my first two girls. Never the friendliest of birds, but beautiful and laid well.
