Katey: Yeah I don't think they have powder on their website anymore, it wasn't there last time I looked. So I am just moving on and figure we will use something else from now on. Thanks for letting us know what your farm uses! Jessica that is sorta funny....you took them off guard! Great idea! Yeah I am going to use something else this year for sure. Thanks for posting what you use on your farm. Thanks everyone for your comments! I am going to call the vet and see what she recommends too.
