1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.) Golden Laced Wyandotte, 14 weeks, 2.5 lbs (digital bathroom scale). 2) What is the behavior, exactly. Barely eating, barely drinking, stumbling, falling, sits still and lethargy. 3) How long has the bird been exhibiting symptoms? We noticed her off in a corner not moving, with a bulge near her breast yesterday morning. We assumed impacted crop and removed her from the rest of the birds. This morning, I am positive it isn't her crop as I can feel vertebrae in the bulge and can follow her neck bones into it with my finger.. 4) Are other birds exhibiting the same symptoms? No, none of my other birds are anything but perfectly healthy and acting normal. 5) Is there any bleeding, injury, broken bones or other sign of trauma. A boney bulge in her breast area, crooked neck cocked off to the right. No trauma or wounds. 6) What happened, if anything that you know of, that may have caused the situation. Unknown. She was fine one day, and not the next. 7) What has the bird been eating and drinking, if at all. Dumor Grower/Finisher, mix grain scratch, grass, and the occasional bug. Water. Hasn't been eating much since she was discovered yesterday morning. 8) How does the poop look? Normal? Bloody? Runny? etc. No poop since I separated her from the rest of the girls yesterday. 9) What has been the treatment you have administered so far? Isolation, access to feed and water. When I believed it was an impacted crop, I removed her feed and force fed one eye dropper full of canola oil. 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? I will treat completely myself. A vet will not be involved. 11) If you have a picture of the wound or condition, please post it. It may help. Pictures will be posted. 12) Describe the housing/bedding in use 16' x 16' enclosed run with a 4'x8' wooden house coop raised 18 inches off the ground to allow an additional 4'x8' area of run, two roosting bars one at approx 18 inches off the floor and the other approx 30 inches off the floor, nest boxes accessible from the exterior, a ramp leading to the door from the ground, pine flake bedding (tractor supply.)
