Thank you for the reply, the 14 day is for slaughter is correct, but we don't eat these chickens we have. The bottle states "Not to use wazine17 on chickens that produce eggs" That prompted me to call the makers of Wazine17, they said the FDA says wait 17 days after treating chickens with wazine17 before eating eggs. The 14 days your implying is a "assumption" 17 days is what FDA says. However after reading about the active drug Piperazine on the FDA site as posted in my first post, we believe the 17 day or even if it was 14 day wait period is way to long to wait. If one reads the site I posted they will see why we say that, coupled with what the man at Fleming Laboratories, INC told me, and that is the FDA is being very, very conservative as to the 17 days wait period. That being said, we decided to go ahead and eat the eggs after about 5 days and we feel safe doing that.
