I have been reading some of the forums and decided to join the group. We have kept backyard chickens for 12 years now. We have had a few experiences over the years with illness, egg bound hens, predators, etc. Recently I have been reading about roundworms and treating with Wazine. I haven't done much research on this topic and would like to know if the eggs that must be discarded for the 17 day period could possibly be incubated. Has anyone had any experience with this, or is there someone who could direct me on this topic? Thanks very much!
