Well, I went and bought a real incubator because there was just no way of keeping the homemade incubator at the proper heat and humidity. I disposed of all the eggs that I had, except one duck egg. All of the eggs I disposed of were mush, except one and that was the oldest egg of the bunch and should have hatched, but I'm afraid something went wrong with that one too, since the bird inside looked very strange and was definitely not viable.
The duck egg just hatched out of my internet bought incubator and has leg problems. I'm guessing its due to the early days of being in a bad incubator. I am hopeful that the other three eggs that I put in the new one, and were never in the homemade one, will be viable. I'll know in a few weeks!
