We had our first chicks hatch today to our Barred Rock hen, our first time having a brooder succeed. Being inexperienced with the whole process, we did not separate her from the flock and after two weeks noticed that she was getting pushed off the nest so the other hens could lay. I built a run around her that was about 2' by 10' on the back wall with wire above her and kept water and food available. She had moved all 5 chicks off the nest, and after over three hours off the nest I noticed that there was a chick that had died at the bottom of the nest. My wife and I decided to remove the remaining eggs and the dead chick. After removing the eggs I noticed that two had what appeared to be signs of chicks that tried to hatch. I proceeded to examine the eggs and I popped off the 1/4" piece of shell that had been pecked loose, and the chicks mouth opened. We immediately set up our bin and heat lamp that we had just put up from some day old chicks that have been moved out to our small coop and run. The chick hatched and is doing fine. My question is now that it has been 5 hours after hatching and about 12 or more hours after the first five hatched can this one be reintroduced to the hen or should we try to hand raise it?
