I'm pretty sure my hens have lice. There are little tan bugs on them. I bought two products today, hoping they would work. I have the MannaPro All Natural Poultry Protector spray and I also bought Permethrin Prozap Insectrin Dust. Is anyone familiar with these products or have another suggestion as to what would work better? I'm going to thoroughly clean out the coop tomorrow and disinfect the whole thing. Also, should I use bleach water to disinfect? Or would white vinegar do the trick? Thank you.
