Mowed my yard this morning for first time of the year. Had area with a lot of leaves and others mainly green grass. Bagged separately. So, put both separated on plastic Tupperware lid and watched. Wow! They dug into both but saw them eating grass just like lettuce and scratching through leaves pecking. Understand natural to look for seeds and bugs and they seem to really dig it. Did I do anything harmful or rewarded them and found some cheap food?
