Safegaurd? Is that like Frontline Plus? Do I put it on the back of their necks and if so, how much? If I do this will I need to do it a second time or one time and done? I get so scared doing this kind of stuff especially when the product isn't made for chickens.You would think there was something out there labeled for chickens that could be given orally or just the drop thing like for dogs/cats. Plus my chickens are just a little over a pound and my sick Lilybug could possibly weigh less then a pound. I don't want to overdose them or make them sick.Thank you for your help.
