I have been keeping a healthy little flock without the use of many chemicals, my chooks happily drink a bit of apple cider vinegar & soaked garlic and will eat black pepper, natural yogurt, comfry and any other herbs from the garden. I control pests in their house with pyrethrum spray and use dolmite to sweeten the soil, but I have had to use a commercial dust recently for feather lice as they got a bit out of control. They are not bio-secure as they range and get visits from brush turkeys, doves, possums, mice etc and they eat lots of bugs so I suspect that they are always carrying a low level of worms, so far they havn't shown any signs of a heavy or unhealthy worm infestation but I worry if it's just a matter of time ! So I ask you what natural remedies you use and in your experience what works well for eliminating the common chook pests, i.e. worms and lice/mites ?
