It started happening today when I took two of my chicks out onto the grass. One of them fell down and just couldn't seem to get up again. To get u again, I have to help it. It can walk around, eat and drink fine however, it's just not as 'energetic'. I bought them last week on Sunday and they both seemed fine. I heard that newspaper isn't a recommended bedding and it can cause a disease in the feet but I'm not sure what it is called. Please help!
