Has anyone had any experience with using Sump Oil for treating mites on the chickens legs. My neighbour has insisted I take a bucket of Sump Oil to try on the chickens legs, so after about a month I decided to take it but haven't put it on their legs yet as I was thinking of just chucking it out, sounds like a pretty extreme idea. It's Sump Oil for a car I think, it has the same consistency as syrup so would coat well and I reckon it's poisonous enough to kill any mites in a 10 mile radius of each chicken.lol. But will it burn their skin or hurt them in any way. Any Advice Is Accepted.
