This chick (either a pure Banty Cochin or BC/Chocolate Orp mix) hatched yesterday afternoon, but has progressively gotten floppier. After moving, the chick flops to the ground and gasps and makes a clicking noise. The Chick's umbilical is inflamed and looks... cracked. I'll have to get pictures. I put it in the brooder under the heater plate with the other chick that hatched out last night so I can access the sick chick without opening the incubator while other chicks are hatching. I put some antibotic ointment on the umbilical, gave it some water and put it under the plate. Is there anything else I can do, or is it a lost cause at this point?
