I tried to introduce my young chicks to the older hens today. Things were going well so I went about my day for a while when I noticed one chick was laying on the ground not moving. It seems that the hens attacked the back of the chicks head and exposed it right down to the skull. I removed all of the young chicks and separated the injured one from the rest. At first she seemed to be almost in shock but several hours later she seems to be acting mostly normal. Does it seem like she will pull through? Also does anyone have any recommendations when the time comes to try to introduce the young ones to the older hens again?
