Since you mentioned healthy and unhealthy... I thought of this. Peachick born with splayed legs, pic probably taken on hatch day. Second picture is the same bird with his (or her - unsexed) legs taped together, you can only see a teeny bit of the blue tape, but he is standing!
I'm not sure if you're interested in non-chicken babens, but these are peachicks, I dont know what breed. 3 male, 1 female, but not sure which one is it the foreground. Young but I never got a hatch date.
