You need egg food and an incubator to keep the chick warm,

feed it with a spoon with the edges bent up make sure it is not too hot though and feed very small amounts at a time you will need to feed him/her every 2-3 hours even through the night and you can decrease this as the chick gets older....if possible though get a nest box and see if mum will enter the box and feed her chick


they are very good at rearing their own young and hand rearing should be a last ditch attempt
