This is excellent advice! Try to follow these instructions, SAVE THAT BIRD!This is all information from the link I posted for you. This information is used to help control and/or treat the ailment. At this point though with your chicken being in desperate need of a treatment your best bet would be to find an avian (bird) vet in your state. You may lose this bird also if he doesn't get treatment right away and no one wants that to happen. I can send you a link for an avian vet in your state if you wish.
- In areas with a history of gout, feed protein should not exceed the standard breed requirements. The raw materials should be carefully monitored for adulteration with urea, which might be one of the reasons for increased uric acid production. Feed dilution should be practiced when gout is observed. This can be carried out either by partial dilution of feed with grain source or by entire replacement of feed with pure grain sources (ground maize) for three to five days to reduce the exertion of kidneys to expel uric acid.
- Ample numbers of waterers should be provided to encourage ad libitum water intake. Similarly, the waterer height needs to be adequate according to the size of birds.
- Provision of urine acidifiers like vinegar, potassium chloride, ammonium chloride and ammonium sulphate through water/feed seem to be fruitful to reduce the incidence of gout.
- Kidney revitalisers play a vital role in boosting up the kidney function, thereby facilitating the flushing of accumulated urates, and need to be used in water. This can be used as a preventive measure in flocks with a previous history of gout in the initial week of chick’s life. It can also be used as a prophylactic in water for 4-5 days continuously, for effectively controlling the gout mortality.
- Provision of methionine hydroxyl analogue, diuretics, coconut water and so on, has also been found be beneficial in controlling gout
Again, good luck
