The fan went out recently on our Genesis and when hubby went to look at it today while I was candling, we discovered that the heating coils had melted the plastic stuff that holds it in place! YIKES!!! No wonder my last couple batches of eggs have had unbelievable amounts of blood rings. I'm so disappointed about losing so many eggs, but glad we have a reason and now it can be fixed. Unfortunately I have eggs due to hatch next week and all the eggs that were in the bator are now in my hatcher so I'm going to have to either build or buy a new incubator since I have staggered hatches. All in the name of a hatching addiction.... I mean hobby.
