They just hatched on Saturday. It is actually one if the little bigger ones. I have 2 that are just tiny but running around eating and drinking.
Have you tried using a little dropper to try and get the vitamins and water in its mouth? Impossible task I know. How old is it? If it's more than a few days old try and tempt it with some ground up meal worms or de shelled peas?
I wish I could be more help. I have a little duckling who is so tiny in comparison with the others. Im hoping it will be ok as its eating and drinking and running around and squealing! Think I'm going to weigh it tomorrow and every few days so I can tell its definitely growing.
