Hi there, i'm a little confused about the dosage of safeguard because there's a post that says to give it like Valbezen one dose wait 10 days and dose again. Then there is another post same people are saying give 3 days in a row. Can someone please clarify which is correct? I have underweight hen that round worms were found in her stool. I gave 1/2 ml liquid safeguard on Wednesday. Thank you,
