the guinea eggs have been in the bator for six going on seven days now. after a rough start of trying to get the temp just right after the first couple of days, the temp is perfect at 99.5 and 40-45% humidity. i candled a couple eggs even though it may be alittle soon. i didn't see anything i think i should be looking at. no dark ring around the egg or spider viens shooting though the egg. i did notice that the yokes didn't float in the eggs as i turned them near the candle(you know, like a bubble level). what does this mean? there was a dark mass in the center but was not round. it was almost rectangle shaped. sorry for the ignorance. this is my first hatch ever. what is going on?
