Hi all, I have 19 chicks who are about 8 days old ( give or take due to delayed hatching) and all but one are doing fine. This one chick is quite large for a Silkie chick and originally it was up and moving about fine but in the last 2-3 days its started walking on its hocks and using its wings to scoot round and to move. There is nothing wrong with its feet/ legs that I can see, there is still blood flow and movement so they aren't broken or anything but I just don't know why he/ she isn't up and moving, why this is suddenly a problem? At first I thought that maybe it was because it is quite large and a little tubby, so I thought that its weight might have something to do with it but now I'm not sure. Other than that everyone else is fine and no one else has any problems. Any thoughts or ideas?
