Hi there, I have noticed over the last week that some of the droppings being left by 1 or more of my girls doesn't look right. The poo just looks like loose blobs of black tar, I am thinking maybe a sign of worms?? But have not seen any worms as such, the girls were wormed with a treatment solution from the pet shop around 1 month ago. I have been told that the herb "wormwood" is good to grow around the yard & that the hens will eat it as they need to keep the worms at bay. Has anybody else tried Wormwood as a natural alternative to the chemical treatments??? Any ideas about what could be causing the black tar poo??? Is it still safe to be eating the eggs???
