We recently bought two Rhode Island Reds, and then got excited and bought two Cochens. So the reds are about three weeks older than the baby babies. Unfortunately this morning I woke up to find one of the baby Cochens had passed away. The older ones have been separated from the younger ones, and she didn't look like anything had happened (meaning blood or obvious signs of disease or illness) Anway, I took her out of the baby cage once I found her and now her sister won't stop cheeping looking for her. It's breaking my heart. Should I find her another chick close to her age so she isn't alone? Will she be alright and bond with the older ones once she's big enough and everything will be fine? We're new to raising chicks, and I know things happen, but I feel really guilty about her passing away.
