the feed is correct.
maybe do a search on here about sugar water or electrolites and see if you find something. keep offering it water like you said your dad did. it my just need a little jump start -- the sugar water would help with that.
i will see if i can find you some links.
I wish i could help you. I have herd to give them sugar water, or electrolites, but I do not know for sure what to do. what are you feeding them besides the eggs?
