I just had to do CPR on a chick that it's mom accidentally laid on ( she laid on its neck). After a few grueling minutes of CPR and a rush inside to my brooder and the heat lamp. The chick is breathing on its own and resting under the heat lamp. I will return it to mom when it is strong enough and can move around. And yes I will do it at night. Just thought I would share my exhilerating tale with everyone. PS if it makes it I am going to need a GOOD name for it. Suggestions?
