If the sac is still reducing stick with it for now. Without seeing the condition of his yolk sac it is difficult to advise you. I know infection is a real danger and the incubator can be full of bacteria. I dont advise a combi lamp these only really work well in an open table. If this is all you have then a separate tub so he is well away from any direct heat. What is needed really is a good background heat. I f you have to use the incubator then make sure tub is very clean and you have jelly or I believe Sandy has used Vaseline, one hatchling in a tub may be ok. Please be careful when handling and bath in lukewarm clean water.
