I picked up a liquid wormer recommended and stocked by the local farm store and have treated the hens prior to their beginning to lay. Upon looking at the label, it states not to give to hens that are laying for human consumption - (is there any other kind of consumption?) Now I'm worried about giving it to them since they've started laying. The brand name is Wazine 17 - contains Piperazine Base as the active ingredient. Is it safe to give and then consume the eggs?? I appreciate the input and will take suggestions on alternate products. Thanks!!
