So I got a text from someone who I sold ducklings to, She's having a problem with one of them, She says the one of her ducklings has no use of it's left side, He eats and drinks when they feed him, They aren't sure what to do for the duckling and they're a busy family that aren't home enough to watch and take care of him 24/7.. Any advice? I'll ask for a picture of it if that helps.
