Quote: Porcelains are made by breeding buff to lavender. After a couple of generations, you can breed them together, that is what I have, pure porcelains. At some point, people breed back to one of the original colors is that color is fading. If you breed a porcelain (buff x lavender) you will get more buff color than lavender. Probably in the next generation, no lavender. Lavender is actually self-blue, and blue, is diluted black, so it probably won't work if its the black leakage you want to get rid of.
How far apart are your temps? It they are in different areas of the incubator, they could be different by up to 1 degree. If they are all close inthe same area, then they should be almost the same. I just bought the new Accurite, I think its called. all in one, reads humidity, high and low temps within a 24 hour period and resets itself at the same time every day. Its about 4 inches square and 1 inch thick. Has a magnet on the back so you can stick it to a metal shelf. I love it.
