One of my bantam Orpingtons hatched and was doing fine until it tore the umbilical cord. It bled for several minutes until I was able to stop the bleeding with cornstarch. It is doing great except for walking. It doesn't have spraddle legs, but it just can't seem to move its weight forward to stand. It's legs are working great otherwise, it just can't stand fully. It doesn't seem weak, other than this issue. Any ideas?
