I am worming my chickens with Wazine today. Which is the best wormer to use after. I have read so much on this that I am confused. Should I use Ivomec,vallbazen or fendendzole? I just want to make sure I am covered. Also I have a broody that has just hatched chicks? What do I do with her? I am afraid to put the wazine in her water as the chicks drink that water too. Should I wait to treat her til the chicks are older as in about 4 weeks? Please help me figure out which is best. Also I have read to give them probotics. Do I do that after the worming or put it in their food during the worming?
