I got a baby chicken as a gift. I have no idea how to care for it. It might be a week or 2 weeks old. I have the food and everything. Ive been keeping it warm with a heat pack made out of rice and cloth. Its my second day and it looks like its yawming. It opens its mouth alot. It can walk and eat. Im scared. Is it normal that it opens its mouth??? I really am freaking out.
