I was wondering if it was safe to give my hens 2 different meds at once. Right now I'm on the second days of treatment with Tylan 50 shots. They really aren't any better. Still having a very hard time breathing. So I am beginning to wonder if it is worms instead. So I am going to buy the safe-guard for goats. Can you give both at once?? They are feeling very skinny!! Trying to help them before they die!!
