A few questions regarding Wazine: 1) Can I leave out the gallon waterers that have Wazine in them for a week or so, and let the girls and boys drink over a period of time? I have other waterers out for them that don't have Wazine in them. 2) Why do you have to throw out the eggs for two weeks after worming them with wazine? Will eating the eggs make you sick? Or kill you? 3) Can you incubate the eggs, or should they be thrown out too? 4) Do I have to follow up with another wormer, or is just the Wazine ok?
