Hey all. Looking for some advice. One of my chickens is much larger then the others, they’re all the same age. She’s got a hump and her tail feathers sit down now instead of up like the others. At first we thought she was egg bound but now don’t think she is. She’s eating and drinking but stomach is swollen, is waddling and doesn’t move very fast. I know we’ll likely have to put her down but am wondering if anyone knows what’s up with her by looking at the photos.
