I am by no means experienced in the innards of poultry. Usually if I'm handling a chicken's body, it came from a bag in the freezer. This is a 1 year old barred rock hen. She showed signs of illness for the last two weeks. It started with: Idly hunching in the coop with feathers fluffed up Loss of appetite Not roosting properly Foul smelling diarrhea Clumsiness As things progressed, it also included: Clear, white, and green diarrhea Loss of vision Sleeping standing up Empty crop Loss of color in comb Tail kept down Dramatic loss of weight After she seemed to make no improvement in isolation in our very warm and cozy bathroom, I gave her a bath to get rid of the crusted poop. That's when I found the very swollen abdomen underneath her vent. It was about as large as an egg and a half under the skin. No redness and no loss of feathers, the skin was just stretched out. I treated her for two days with sulmet, acv in water, yogurt with wheat germ, vitamins, and chia seeds, and she did eat a decent amount of breakfast oats. Unfortunately, it was clear that there was little we could do for her, and she seemed to be in pain. This morning my boyfriend took her out behind the barn and humanely ended her suffering. I spent a lot of time reading the thread on swollen abdomens and read up on others' experiences with necropsy. I knew that I needed to find out what was behind the swollen abdomen walls in order to determine the health risks for the rest of my flock. Based on my reading here, I figured I would open her up and find a fluid filled cyst, an impacted ovary filled with rotted or half formed eggs, or a hernia with all of her organs displaced. I did not find any of those things. What I did find was infected, rotting, putrid, unidentifiable (to the uninitiated) flesh. Maybe it's a tumor? Maybe it's the ovary after all? All I know is that nothing looked like anything anyone else had posted, and it smelled unbearably horrible. I'm going to attach the images here. The abdomen on the live hen. What it looked like with the skin peeled back Being totally unsure what to do or where to start, I just cut right into it. Note the green and yellow hues. I did try to cut around it on the top right of what you see, to try and see into her body cavity. It just wasn't what I expected to see and I couldn't identify anything at all. All I found there was more rotting green flesh and that's when the smell was too much and I had to stop. It was very strong. What are the holes going through? Were those organs and this mass grew around them? I don't have any answers from this except that we definitely did the right thing in putting her down. I would really appreciate the thoughts and opinions of you byc folk.
