Im so sorry for the difficulties that you went thru and the losses that you suffered, i hope none of the babies suffered too much, and that passing was swift as possible. The one recommendation i would deff. make is to sterilize that incubator very well, clean it well with chlorine in the solution. to sterilze the fan motor, wafer etc that are hard to clean effectively, i put a pan of clorine in the incubator and close it up and let the chlorine fumes penetrate everything for a couple of days, do not run it durring that time. After that, open it up and let it air out for a few days. Im really hoping that none of your probs are viral or bacterial in nature. Best of luck with future hatches.
