It could be considered an allegory, although it's categorized as a comedy escape drama. The moral could be that love conquers all, perhaps, because the two main characters, the chicken, fall in love and try to escape.
I think the moral is that you cant run someones live and you have to do what you want in life. You have to live the life you were mint to live. The chickens are trying to get freedom from the farmers because they are going to cook all of them. So they escape to live somewhere safe.
