If I give my hens this, Agrimycin-343, how long until I am able to eat the eggs? Everything ive read says to not use it on chickens that produce eggs for human consumption, but doesnt give a time when it would be safe again. I have 2 hens that have weepy eye and one kinda barks... I have never heard her cackle like the other chickens. I am gonna seperate them from the rest again and I want to try this stuff to see if it works. All the chickens have been dewormed and were on a course of Duramycin a month ago. Id hate to have to cull the 2 hens.. They are both french copper marans.. One blue and one black. Oh, and neither has laid us any eggs since weve gotten them except once.. and that was a day or so after they came home. Weve had them for about 3 months. They were sold to us as year olds..
