My chick question is: My bantam's are running at eachother and jumping up and kicking at eachother. Is this playing or fighting? My duckling question is: My duckling with the yellowish belly seems to be very protective. When I hold the other duckling the "yellow Belly" duckling will charge me and hit its head on my hand that is holding the other duckling. "yellow belly" did the same thing this morning when I was holding one of the chicks. Whats the deal with "yellow belly"?
