I have treated many problems with my chickens. I have only lost two both chicks. I find that time tells the difference. We are so quick to jump at the idea of death being a cure for expected immediate healing. I have a beautiful snow white hen who fell off my picket fenced compost pile and caught her leg between the boards. I have no idea how long she was hung like that but when I found her she could not stand on the leg. She was about 7 weeks old. I brought her in and but her in a swirled towel so she could be off the leg but could still sit in the right position. I gave her vitamin water to drink. I kept putting her on her feet. Then I would pick her up gently and with my hands under her I would slowly take away the support of my hands. I was letting her decide she could stand on it. It took about a week before she showed marked improvement and hopped out for a bug crawling by. Outside she went. I sat her down in the run and walked off. She was eating with the other birds by end of day. I said all of that to say this. "IF" at the end of a week your chick doesn't show signs of improvement you should put it down. Let your daughter help you give it physical therapy to teach her responsibility for injury. It also helps them learn that Chickens are as mortal as human beings. Maybe it will help her realize she needs to care for them as thought they are as fragile as the eggs they lay. Good luck.
