Hey! I know it's early to tell, the egg was laid Saturday and it's Monday right now. However I noticed what seems to be chalking already? There seems to be a whiter circle near the sharpie dot (shows which way is up). Is that chalking, and if not, when does chalking start? Thank you, hope this is fertile! By the way the temp isn't really 90, it is more 88-89 because that thermometer goes by 2 and the other ones I have show 88 or 89.
