This is my first hatch. The chicks are 2 days old. I noticed yesterday one chick kept getting on its back and could not right itself. I watched it all day and had to turn it over 3 times. I told my wife we'd have to keep an eye on it through the night and tomorrow (now today). She woke me up a few hours later and we found it on its back dead. Any ideas? I don't want a repeat if at all possible!
