for one baytril will boost your pigeons no doubt about that it surpresses the immune system then as u come off of it u will get a caterpult reaction with it but this is not the way to go good birds good feeding thats the most important thing routine and health if u are gonna treat then do so for 5 to 7 days the required amount of time for most anitbiotics because if u start giving for one days here and there it wont work wen u do ever need it also baytrill is not a last resort medication its very good for wat its purpose is for imo
