Almost all of my red foot eggs have dried out in my incubator witch I don't really understand because I used the same incubator and substrate that I used last year and almost all hatched. I broke open some of the eggs after they were way past due and some had a small tortoise in the egg but the eggs were dried out. I use hatchrit as my substrate and I add water to it about every two to three weeks. I keep the humidity around 75 to 85%. the only thing that I can think off is that my fan didn't want to work inside my incubator so I replaced it and the new fan seems to be stronger. I always put my eggs in cups about 1/4 to half way in the substrate but I don't put a lid on the cups. if anyone has any advise at all for incubating red foot eggs I would be more than happy to here you out because whatever I am doing is not working.
