My deer for some reason go nuts for chicory in the early fall once we get cool nights. I have it mixed in with my perennial clover plots - and you will see the big broad leaves of it in september and then somebody flips a switch and the deer come thru and hammer the crap out of it to where you have no idea the chicory was ever there. The deer eat it some in the summer, but for some reason there is a trigger in the early fall where the deer seem to specifically seek it out on my place. You do have to watch your varieties as there are different varieties for different applications. It can even grow wild. I know some folks plant plots of of it as the primary planting.
