sorry that it took so long to reply, I got my temperature's under control but have another question. I checked on my eggs this morning and noticed one is turning slightly yellow from the top heading down. I'm not sure what this means. could this be caused by water dripping off the lid on top of it? I noticed one of the other eggs has a small spot on its side like that. but this egg is almost halfway covered. does this mean the egg is going bad? it still has some veins. I will post a picture of it once I get home. thanks in advance for any information.
