Cool!! In my experience, once they start actively expanding the hole, it's not more than a few hours till hatch. So it sounds like you're getting close!! Keep in mind, however, that every breed/line/generation/individual is different, so don't panic if your duckie takes a break or two between now and hatch. Just watch for overall activity. Danger signs are: Lack of progress for 24 hours or more combined with noticeably decreasing strength of activity and/or peeps over the same period. Keep us posted! And of course--please post pictures when you're baby arrives. I am SOOOOOO jealous. I am having serious duckling cravings. I have a batch of eggs in the bator now, but I don't think they are developing, so I'm going to have to start over soon with a new batch, and that means waiting even longer for babies!! I have a batch coming from Holderread at the beginning of April, so at least I know that's coming, but it's too long to wait. You're going to have a baby in less than two days!!! Hurrayy!!!
