You need to try to find an avian vet in Kenya. Dr B can not tell you what is wrong with your bird without an exam and tests. If there is not one within a few hours, then find a reputable breeder in your area. I have found that in other countries, a good breeder might have meds and experience to help with sick birds.
It is best to find an avian vet, so blood tests can be run to find out exactly what is wrong, so the exact treatment the bird needs will be administered. Otherwise, it is all guesswork and often the bird suffers long and eventually dies due to the wrong treatment being administered.
