We had 5 khaki Campbell ducklings hatch on the 3rd of June. 2 of them needed our help as they were stuck and the membrane was drying on them. We just peeled it back a bit and let them get out themselves. Weren't sure if they''d make it through the night as they were very weak but one was perfect (couldn't actually tell which duck it was as it got out and joined the other 3!) The other one seems to have no balance at all. It always leans to the side and falls over. We looked online and the closest thing we've found is Stargazing but it doesn't actually. Look up before it falls. Other than that it eats and drinks great and can get to where it wants to go and is very active. Has anyone heard off this? Any ideas what we can do? Edit We have him on bits which include b and niacin. He's been on them since Monday. And is on chick crumbs. Non medicated.
