What kind of worms did you get from the lawn?? & a whole summer w/ no eggs?? What did you de-worm them with?? I just de-wormed mine on 8-5 w/ wazine as a preventative measure, I have some Ivermectin pour on being shipped from amazon, should arrive this week & will use that as soon as it comes in. All told, it'll only be about a month w/ no eggs, not the whole summer. That seems like a long time to go w/ no eggs. How old are your chickens??? I'd love to see pics of them, esp the pencil laced one, I want one of those in my flock!
