We just got some baby chicks a few days ago. I'm not exactly sure how old they are, but I think about a week old. One of our EEs, Kohla, had what looked like a prolapse. I was sitting by their brooder watching them when she squatted and started chirping really loudly, like she was in pain, and pooped. I picked her up to make sure she was okay, and her "butt" was hanging out of her vent. We put vaseline on a Q-tip and pushed it back in because her vent was way too small for fingers. I'm not really sure what to do, if there is anything. I'm worried it might happen again when I'm not there and then the other chicks will peck at it. Please help. Thank you.
