I'm doing a school hatch project for my 2nd grader's class (unexpected, as I won a giveaway for a icubator rental and eggs). I candled the eggs last week at about day 11/12 and showed the class the air cell, and the dark spot section. The classroom has 2 walls of windows so it doesn't get very dark.
When I went in today to put them into lockdown I candled them and marked the air cell and an idea of where they might pip (from what I read on here). I'm concerned because they look very similar to what they looked like last week. We've done a good job of keeping the temp accurate, and the humidity I thought, but no one is around the check on them saturdays or sundays.
What do you think? I thought they would be fuller on day 18. Most of the eggs look similar, but like I said, it's hard to see much because the classroom doesn't get dark enough and I didn't want to haul eggs all over the school looking for a dark place.
Are they just underdeveloped? or is there anything I can do? I'm just praying a few hatch because the kids are just SO. EXCITED. :)
