weak cockerel with posible respiratory illness help me to diagnose it, please

[beautifulchick]

It does look like a lot of urates. Is the chicken drinking enough fluids? I am not a vet, but sometimes dehydration can cause more urates in the droppings.

water only not much, I think he wants to drink but just drink a little and stops, but he ate the yogurt and I give him vitamins in water with a syringe but I don't know if it was enough. What about the medicines? can you help me?
