Why is my budgie puffy, vomiting, and has dark poop on millet diet?

Thanks for reaching out ab out Beau and including photos. Agree that if too cold with fluff feathers in an attempt to increase insulation. But they usually do not decrease eating, as calories needed to make heat. A darker green stool is often a sign of decreased appetite, increased white and clear urine is increased drinking. Millet is a poor diet as devoid of many vitamins and minerals and is basically the equivalence of potato chips. A wide variety of vegetables is needed, a plant based protein source (beans, legumes, tofu) and avian pellets are recommended. As he is likely ill, a veterinary visit is highly recommended to assess and provide a diagnostic/treatment plan. Provide heat support 24/7. Good luck.
