This sounds like Piku is pretty ill and needs to be seen by a vet. Vomiting and lethargy are both very general signs of illness, and since birds are very good at hiding being sick, if Piku is showing visible signs he should be treated by a vet in person. In the meantime, keeping him in a warm hospital cage with access to food and water may help, but if the problem persists, vet care is needed.

Thanks for reaching out about chicken. A radiograph should be taken as ingested foreign bodies. Small pieces of metal with lead or zinc, are very common causes of regurgitation in birds. These metals usually show up well on radiographs. Other foreign bodies can cause gastrointestinal obstructions, resulting in vomiting. Liver or kidney disease, a viral disease called avian bornavirus are other possibilities. Antibiotics in the water are a poor choice for administration as there is no control over dosing. Sick animals drink little water. A veterinarian with more avian experience is recommended. Good luck.

If he is not accustomed to flying around in any fashion, than I would not be terribly worried by this unless it happens a couple more times. Even though they are birds and you'd think they should not suffer from motion sickness, it definitely can happen in fledglings. Whether or not it was motion sickness, stress, or something else that caused this incident will be evident soon enough it the symptoms continue in any chronic fashion. If this is the case, you will need to track down your nearest vet comfortable with treating avian species.
