A chick was pipped this morning and it was the last one to hatch. I checked on the rest of the chicks this evening and it seems that the siblings got too curious and started to peck away and this chick. He isnt hatching out correctly. He is almost out except some shell on his belly/bottom. The hen has left it to the side and its siblings were still pecking at it. I have brought it inside now and it is on a heating pad. What should I do? He is breathing and peeping still.
