I haven't ever heard of them eating chufas either but they are dang sure doing it!
Just my luck I guess! Seems like the harder I try and the more I do for the game the more mother nature fights me.
I've been in Louisiana since Thursday afternoon and come home to this mess.
Oh well! Waiting on it to cool off a little before I spray the worms this afternoon and I'll be burning diesel tomorrow planting more millet, chufas and clay peas.
