My chicken is about 2 months old and one day I check on them all and one of them wouldn't walk on her one foot. I'm new to chicken owning and I had no idea what was wrong. I checked for broken limbs and there was none, so I brought her to my school agriculture class and they still didn't know why she was limping. By this point ( 4 days later) her feet were curling and looked all bruised/ swollen. I did some research and it was not bumble foot or frost bite. She would eat and drink and poop just fine but she tries to walk and has to flap her wings to stay balanced. It's about a week later and her feet are totally black , and bruised on the bottom. One foot is tucked into a fist and the other are curled and some blood was coming out through the nail. I researched curly toe paralysis some but it didn't have the symptoms of the feet turning black. Dead tissue maybe? Looking for some ideas as to what it may be. Im going to put her down she's in a ton of pain and shouldn't have to suffer. I'd still love some in put though!!
