I'd keep their brooder on the floor and put some kind of open top using plastic poultry fence or netting to keep them from jumping out of it, we see some ducklings here with broken legs I don't think you'd want that to happen to yours. Glad to hear the eye is getting better.It has gotten much better.
The problem is their jumpy and keep falling to the floor and hurting themselves but they stand up and like
''dafuq was that?''.
