Cons - Bottle is small and expensive for amount you get, also needs to be re-applied daily
I love this stuff and go though alot of it. I raise polish and the chicks tend to pick on each others tops hats, so I apply this and problem solved. The only downside, you have to re-apply daily and the stuff is expensive. I pay $9 buck a bottle at my local feed store. It may be cheaper on-line.
This has saved many chicks of mine as after the "pasty butt" is washed off, the newly washed area is sometimes targeted for pecking by other chicks. A little of this on the bottom and it tastes bad to them!
