You need to make sure that they have food and water. Chicks need a particular type of food called "starter feed," which is higher in protein than regular chicken feed. They also need access to fresh water at all times. You need to provide them with a warm place to stay. Chicks need a temperature of between 95 and 100 degrees Fahrenheit for the first week of their lives. After that, you can gradually start lowering the temperature by 5 degrees per week till they are fully feathered and can regulate their body temperature. Keep an eye out for signs of illness and injury.
