Received two Serema (teenaged) chicks from friend. They have always been with their mother and have little to no human contact. Since yesterday they haven't eaten or drunken water from the waterer yet. One of them is looking abnormally tired while the other is chirping away. I hand watered both at first and it worked but now they won't even open their beak but instead shake the water off of their beak. I tried scrambled eggs but they would just peck at it or ignore. How do I get them to drink and eat themselves?
