I also have tried a 22% and they didnt seem to eat it as well as the 24%. I have also tried a 30% and they wasted it way more then all. So i went back to the 24% and called it a day!Our TSC has this as well. I bought some and have been blending it with their current feed (a 22% chick starter, non-medicated). They are throwing so much of this blend, that I am wondering if they love the new or love the old one. They ate and didn't toss the 22% nearly as much as this 50/50 mix. This 24% definitely smells different than the 22% (different brand) that I had purchased at another feed store. I was so happy to see this at the TSC, but will have to determine if it is the one they like or not.
