I'm glad we could help you! Its not too expensive either. I just got some with my poultry dust to put it the coop. ALWAYS consult BYC before going to TSC. They never know anything about chickens and look at you like your crazy. We can tell you exactly what you are looking for, where to find it, and what to ask for. I know this place is a life saver for my chickens. Never be afraid to ask either. You will almost always get great advice and priceless information. Good luck with your chickens, be glad you are doing the preventative instead of treating an infestation- GOOD JOB!
