the other day i think it was yesterday when i candled the eggs in one of the eggs there were 4 tiny dots that were sort of connected in a line and they were moving, and today i candled this egg again and the 4 dots have sort of morphed into one big dark spot and it looks like it is stuck to the inside surface of the shell! has anybody had this before? what is it? also, the eggs are not using up as much water as they used to, the water pots in the incubator are almost still full from when i filled them yesterday and normally i have to fill them every morning because they are nearly empty! is that a bad sign too?
