Oil is never good in any situation. It turns impacted crops harder and as for slow and sour crops, it slows them down even more. Chickens do not eat oil in their natural habitats and it is very hard to break down and digest.Good info. A lot of other threads said to use oil, so I'm glad I saw this. Are there any situations where olive oil would be of use, or is it just wrong in all situations? What fungal meds would you use?
