Ok so I don't know if I am putting this in the right section but I'm really new to this and I couldn't find anywhere else to ask this question. So I am incubating chicken eggs. The temp is consistent 99-100. My humidity is in the 50s%. I turn my eggs 3-6 hours apart everyday. In the beginning when I turn my eggs the dark spot always floats to the top, or stays on the top of I turn it very slowly. My question is, is there a time when the circle/yolk stop moving and attach itself to the egg shell when the chick starts to develop and blood vessels start growing? I ask this because mine stopped moving like it got stuck. I don't know why else is would stop floating all around. I turn them as much as suggested if not a couple more times then suggested. I have 3 others that are about a week ahead of these and I can't remember if they "got stuck" or just stopped when The blood vessels start growing all over the inside. If their not supposed to stay how do I get them "unstuck"
