Did I ruin all my eggs? I was so preoccupied with the temp and keeping the bator closed that I forgot to turn them at all yesterday! I set them at 8:30 am and turned them for the first time @ 7:30 this morning (so 23 hours in)
turn and odd number of times every day, or they will be 'cooking' on the same side every night. (I turn every time I go to the room and every morning and night so 3 or 5 times a day)
Turning evens out 'cooking side' and keeps the embryo from getting stuck to one place on the shell- the hot spots or areas on an egg can cause growth problems (too fast where its hot, to slow where its cool) leading to deformities.
By turning the eggs you are excersising the embryo and you also have less chance of an embryo from sticking to the side, I think some people don't turn the eggs, or I'll seen other people post. Also, by turning the eggs 3x(or 1x) a day, the embryo doesn't sit one the same side every night.
