My chicks started hatching yesterday morning. The first chick that hatched was really active and seemed ok. This morning she seems to want to sleep and sleep standing up. She seems to want to sleep constantly. She will stand up normally and then you will see her head slowly start to fall till it touches the ground then she'll either sleep for a bit or stand up again. Most of the time her eyes are closed but she does open them sometimes. Yesterday she acted like a normal chick. Do you think she's sick? I've attached a pic.
