I think if you don't have anything except tylan I will go with tylan till u can have baytril
Can't you get medicine from a store near u like I got here ?
Do u need prescription?
I usually have a stock always in my home as here in India it's very easy to buy
Feels like Ecoli infection
Or EYP but I can be wrong
Yellow urates poop might be from Dehydration too
But poop those seems like cooked egg is always EYP
Start Baytril
