Mine got their treat on accident. I was out changing their feed and water getting them ready for "bed" (they are out in my shop for now till the coop gets finished) and a June bug flew into the pen. At first they wanted nothing to do with it and didn't want it touching them. Then one grabbed it before I could and then it was was "keep away" and "take away". Thank goodness I got them some grit. At 3-4 weeks old them things are to fast for me...can only imagine how its gonna be when they get much older.
LOL, my chickens are almost like goats....they will eat almost ANYTHING!! One day I saw one of my girls with something in her beak, beating it on the ground. At first I thought it was a grasshopper.....but it was floppy?!?!? When I looked more closely I realized it was a baby mouse. She'd found a mouse nest (I'd just moved a 55 gal drum) and she was cleaning up. PROTEIN, yum!!!
