Aloha! Some background: I live in Hawaii and we raise/rescue the wild jungle fowl here (kind of wild chickens). Not true chickens because they do not lay eggs year round, and have "seasons" for mating and laying.right now, it is chick season..... Specifics: we rescued 2 baby chicks when they were a day old. Raised them indoors for a few days, then found 2 more day old chicks, and raised them indoors for a few days, then started their day pen. During the day, they are outside in a pen, and we bring them in at night. The biggest chicks as about 6 inches tall, the little chicks are about 3 inches tall(measuring to their backs not heads) They get along fine. Then, we rescue a fifth chick. It is halfway between the big ones and the little ones. The new chick: The new chick was one of three. Two of them were killed by a dog when they "broke into" the back porch. The third was abandoned by their mother after the incident. One day, it too "broke into" the back porch, luckily we were able to grab it before he dog got it. This chick is VERY loud! The weird stuff: everyone hates the new chick! Al first the other chicks didn't seem to care, but on in a while it would get a peck from them (we chucked it up to pecking order being established). Then, a mother hen (outside the cage) came by with her flock of 11., and became obsessed with chasing the chick around, trying to attack it from outside the cage. She has been across the yard, and left her babies to try attack this chick! The other chicks in the cage also attacked the chick. The had been together for about 2 weeks, but last night the one chick was a crumbled pile in the cage....it is still alive, and now isolated. Question: Is it weird for a whole bunch of chickens to seemingly randomly attack and hate one chicken? Could it be telling us something about this one chick? Or maybe they do not like how loud it is? Thanks a bunch!
