I have kept chickens since I was 15, thats over 20 years.(waves fist in air from rocking chair on porch)However this is the first year I have had more than 10. I have never really needed to medicate my chickens before, just vaccines and an occasional wormer. I often end up replacing the contents of my first chickie aid kit because it expires. They way I collect eggs for incubation, it is nearly impossible that I have EVER inbred chickens. I select breeders and toss them in a special pen for nookie time, collect the eggs and hatch them. If anyone is hooking up with their sister or whatever, those eggs get eaten so it doesn't matter. The fact that you would bring up "losing a whole flock in a week" and "medicating every bird in the yard" etc etc to support your inbreeding theory is hurtful. Those were 80% chicks I purchased else where (Gold Feather) and the very first time I'd delt with contagious chicken illnesses. You are either accusing me or Goldfeather Farms of severely inbreeding to the point of animals being unable to thrive. I'd like to see proof to support your hypothosis, or appology
