Hi set up a brooder and take care of them yourself get Cocunut water asap that's what saved my baby I had to pull him from nest box at 4 hours old and today he is 10 days old doing great.
You must get phase 1 handrearing food and a syringe, coconut water brooder with the right temperature and humidity. Once you have that sorted then give the babies Cocunut water every hour for the first two days, but only a little like a few drops, they need to get hydrated also check there intestines if it's black they are very dehydrated it's a clear sign to look out for. Then you need to figure out there age so that you know how much to feed them the formula have to feed them every 2 hours post pics of your babies. Some times when the parents can't get a feeding response from the babies they actually can injure them and they can die, that's what happened to my one baby hence I had to save the little guy when he was only 4 hours old you can easily save yours it's not that difficult you need to read up on how to feed them how to place the syringe in there mouth and make sure the temperature and humidity is correct but also the food and coconut water must be at 40 Celsius when you feed it to them If the food or Cocunut water is to cold you theyncaj get prob with there crop bad problems so make sure the food is not over 40 Celsius because that can create crop burn very painful and if it's to low you Wil have probs with sour crop etc.. Make sure you have a thermometer that works and a device that correct to check the humidity and temperature.
