I just tried it and your right it is so funny!!!! They loved it and would steal it from one another too! Any other yummies to try, I am new to having my own chickens. Helped my granny as a child but that was 25 years ago lol.
Last year mine started with zucchini, yellow squash, and cucumbers quartered lengthwise. Once those were mastered they loved halved cherry tomatoes. Bananas and Watermelon were a big hit too.
