**Q: Can you use for goats?**
A: We do not know; sold all goats some time back.  We have sheep, but have never tried on the sheep. We discovered, that if you have chicken free range with other livestock; they have just about controlled the fly problems.  They scratch around in manure and eat the fly larvae.  Very good results & the eggs are a wonderful gift each day!

**Q: How many 360 gram packs are included at this price?**
A: Dear Patrick, this price is for a case with 6 packs of Justifly 360gram. You just need to mix a pack into a 50 pounds bag of your preffered mineral (so 6 packs is mixed into 300 pounds of mineral). Just to let you know, one pack of Justifly 360gram can treat 2 animals during 6 months of fly season in average (a case with 6 packs treat 12 animals in the fly season). So, you can control the development of horn fly, face fly, stable fly and house fly for less than $.04/head/day. Simple, economical, fly control!
