PLEASE help! We're having really bad problems with a strange and awful tcp-like taste tainting our backyard free range eggs. Thought we had sorted it a few weeks ago but it has come back... Causes we thought we had identified and subsequently eliminated/removed: freshly painted egg storage hut, earth powder, farmer spraying fields neighbouring field, home mix feed with molasses etc, mite powder mixed into dust baths.... But it has come back so must be something else !!! Any experience/ suggestions please?!?!
