Newly hatched chicks
Do you only have one chick? It really needs a companion to help it learn quicker and keep warm. If you could post a photo of your brooder setup that would be greatly helpful. Have you dipped it's beak into the water and tapped your finger in the feed to get it curious about the food? I wouldn't worry too much about it though as the chicks can live off of their yolk for many days after hatching.
