Hi Chicken owning friends, I need some advice on different methods for getting rid of chicken lice and their eggs, I just can’t seem to keep up! I have 32 birds, been dusting with DE and spraying with Poultry Protector. I have used this method before but it’s not working now. I have some Prozap but thought that was pretty harmful to the birds. Should I try this? Other method suggestions are much appreciated!!
