We just hatched 2 ducklings yesterday, whose mother vanished one night a few weeks ago. We didn’t have an incubator for the first 3 almost 4 days. We just used a heat lamp as we were awaiting the incubator. They’ve stayed in the incubator but only 2 out of 10 eggs hatched. One of the ducklings is fine but the other one was born with a small bump on its head, what seemed like wry neck and a bit of a curled toe. The neck and toe seem to be improving and the bump seems to have started draining but he still seems weak. I’m really more concerned about the bump. I’ve put neosporin on it but not sure what the bump is and if is something that will go away or if it’s something harmful to the duckling?
