I just received Denagard I bought from ebay for my sick chickens but I noticed that it had tape on the lid and the seal was broken! I don't know if I should use it but it has a good date on it...expires in 2017. My big concern is when I smelled it, it smells just like rubbing alcohol. ..so I was wondering if I got screwd??? Any suggestions ? Does this stuff smell like regular rubbing alcohol???
