I have a little game bird, she's about fifteen weeks old and she got sick a couple days ago. Her feathers are completely fluffed out, she's unsteady on her feet, sleeps all the time, very cold, and every minute or so she stretches out her neck and 'yawns'. Her poop is normal, shes eating, and shes drinking.There's no coughing or sneezing and her poop is normal. I brought her inside when she began to look really bad. Is there anything I can do for her?
