New chicks... Weak... HELP!
Could you try giving some sugar water to them ? Other's also say vitamins/electrolytes for chickens but if you don't have those I think sugar will be fine for a few hours, not for too long as it causes constipation and you don't want them blocked up Hopefully it will give them some energy to eat some real food and water.
I've read that it is 1 teaspoon per quart which is just over a litre.
Tell me how your chicks get on.
