My step dad found a birds nest with 2 dead babies and one live. He said he had been working in that area and assumed the nest abandoned due to the fact no parent had been there for 3 days. I'm using a heat pack, dog kibble, baby food, crushed worms, and a dropper. I soaked the dog kibble in water and mixed it with the baby food and worms and I've been feeding every 30 min. Any advice? Also, I'm wondering if I should still feed every 30 min at night. Thank you so much.

Edit: unfortunately, he did not make it through the night. I had called the person I knew, however he was having a rough time breathing. I kept him warm but it was too much for him.

Thank you for the advice and help, and I am so sorry I couldn't save him...
