I have several rabbit pens with groups of brooder reared chicks. Waiting out a storm; I sat down on a bucket by pen and began offering the live meal worms. Was first exposure to meal worms for these guys. They were slow to go after the meal worms at first. Three of the 30+ chicks got the picture and started going after the meal worms offered singly by me pushing the items up through bottom of the cage. The other birds then concentrated on stealing the meal worms from the 3 catchers. The catchers put in the most effort but got at least a piece of each prey item.
