A friend and I went in together to order 25 chicks from McMurray Hatcheries. They just came in Monday morning. I picked my 6 chicks up from her Tuesday morning when I got back in town. I had gotten 3 Barred Rocks & 3 R.I. Reds. We brought them home, set them up in the storage tub with bedding, water, and food. I checked on them all day and twice during the night. This morning I was cleaning up my room (opposite end of the house) while my girls (5yo and 2yo) were watching a movie. I didn't hear them leave the living room and by the time I realized that they were WAY too quiet, it was too late. I went to find them and found them in the back room where the chicks were being kept. 3 of the chicks were already dead. 2 were injured. The last one seemed to be fine. Of the two injured chicks, one of them died within 20 minutes after. I talked to the girls, cleaned them up (bathed my 2yo) and put them in time out. I then went back to see what I could do with the injured chicks. One black chick seemed completely fine...I couldn't see any signs of being injured and she's up and moving around, chirping and acting scared but normal. 1 Red and 1 black chick were injured but alive. The injured black chick died soon after however, despite trying to keep her warm and safe. She didn't seem to be able to stand or move very well. She finally flopped around a few times just before dying. Both the injured chicks have the skin split from the vent toward the front about a half inch long. It's a straight split. The red chick is up and moving but I'm really concerned about her. She also has something hanging out of her vent by a thin string of whitish tissue. I'm not sure what it is. It's reddish in color. I feel horrible about it happening and I'm just not sure what to do. These are my first chickens and I was really looking forward to having 5-6 chickens laying eggs. My dad was planning to come help me build a fenced in run and small covered area for them to roost at night this weekend. Is there anything I can do to help this injured baby chick? As tiny as she is, can I do anything without causing more trauma? I'm not even sure that I should try to clean and try to close the wound. I talked with the girls several times yesterday about not going in the chickens' room and not handling the chicks without me there. They knew they shouldn't have gone in there and I'm not sure what possessed them to sneak in there or why my 5yo didn't come get me when my 2yo squeezed the first chick to death.
