Just wait till they start going broody all the time! I swear it's a constant thing. I have one that sat forever on nothing, then gave up for about a week and is now back to sitting and another that started sitting and screeches her head off the second I open the nest box door. My point is, enjoy getting the eggs now before they all start going broody on you!!
Anyway, the eggs are doing good. I locked them down last night because I saw one looked like it was working on an internal pip but I checked it this morning and nothing yet. But several more have drawn down. I think they may be right on time! All 18 have made it this far. One I'm a little concerned about because the air cell has not grown since day 14/15 and I can not tell which side is up because it's a perfect circle air cell but I saw the chick move this morning so we'll see. So far so good overall.
