I saw a segment in a show last week but for the life of me I can’t rember which show it was. I suspect it was just a fill in because i’ve beenback through the TV guide and I can’t find anything likely.
Anyway, they had Josh talking about one of the, often overlooked, dangers of backyard chooks.
In years past dieldrin was a common poison around fence lines, sheds and houses. It has a very long life in the soil, is accumulative in the body and a known carcinogen. Hens that are allowed to peck around contaminated areas pass it through in their eggs. He reccommended soil testing or getting the eggs tested by a lab. Also keeping hens at least a metre from fences or buildings.
Bit scary really because who knows what was used in older suburbs before we bought houses there.
