So what is in laying mash that makes it work? I never use it but my chickens always lay good. I just recently wormed my whole flock and since then laying has dropped off dramaticly. Im not sure if that had anything to do with it but I am trying to collect eggs from my flock and bantams for the bator. I would like to go ahead and get a start on the next generation but I need eggs to do that. I never eat them for 2 weeks after worming to be safe. Is laying mash safe? I only plan to feed them it for about a month. I generally let nature take it course but she is slacking and I'm hopeing this will give her a kick in the head.
