I am new to hatching and raising chickens. We had one egg pip 6 days ago and hasn't progressed since then. You can see it breathe and hear it peep, but won't zip. So we assisted in hatching today, it is breathing and eyes open but won't move around. The feathers look wet but are crusty and it just lays there. There is also a green discharge, not sure what this is and what to do at this point. Any help would be greatly appreciated.
