Hi I adopted a mother hen and her babies who somebody abandoned, it is my first time taking care of chickens, they were in rough shape, over the course of a couple weeks I nursed the mother and babies back to healthy chickens and made them apart of our family, unfortunately one morning the mama hen got over my neighbors tall fence (still no idea how this happened) and his dogs hurt her, she had to be euthanized, in the coming days since then I've built the babies a coop and having been taking care of them, I've since bought two ameraucana, a red broiler, and an Australian authorpe chicks to raise and make them a flock but I still have no idea what the older chicks are if anyone.could help I'd really appreciate it
