Was wondering if Wazine takes care of more than one type of worm...I have not seen any worms but am thinking I should worm as a preventative.I have debated doing this as I try not to medicate but I really don't want a problem to arise as I have a considerable number of chickens now.Is there a good broad spectrum wormer out there? I know some have said Ivermectin...it seems so strong...and how much would you use? and how? How long would you hold the eggs back after worming and could you use the eggs for chicken food so as not to waste them all? Sorry for so many questions but I am afraid not to worm at this point with so many birds at stake.
