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. :)

TIA
 
On Day 18 the egg should be totally dark with only the air cell showing. Sorry......

These appear to be clear, with no development at all. The only "darkness" I see is the yolk.

Well shoot, I didn't realize that was what a clear egg looks liked. I think my mind and from the pictures I remember seeing, that having half the egg have a dark mass like that didn't indicate clear, I thought that was the chick growing area. I'd gone through everything I could find on this site, including that link you shared to help me figure this out. I thought because the classroom couldn't get dark enough that what I was seeing was ok. Apparently not. So discourging.

I looked at *my* chickens eggs (at home) a while ago, before I candled the eggs in the class and there were obviously differences in the 2 eggs--the unfertilized fresh eggs from my girls had a small yolk spot in them on the side, so when the incubating eggs looked different I thought they were ok. Because every single egg but 1 looks like this (12 total). 1 egg last week had a very dark spot in the dark mass I thought might be an eye or something.

So what I'm gathering is if they all look like this, they're clear eggs which means no development. Those odds of all the eggs failing sucks!

Thanks for the help.

I'd honestly have to question the fertility of the eggs. If you had one with a black dot, it could have been the "eye" and had started developing, especially if there were any viening, but w/o any veining and no blood rings, I would bet that if you cracked them open all you'd find is runny yolk and white.

This is what I'm wondering too. After school is out (and the kids are out of the classroom!) I'm going to crack one open and see if I can see a fertilized spot or not. And if not, I suppose I'll be having a little chat with the hatchery I won the giveaway through.

After 18 days of incubation you won't be able to tell because the blastoderm/disc breaks down.

Don't blame yourself for doing something wrong. It takes a few tries at incubating to know what you are seeing. I think it's more likely that the eggs were the problem. So many things can happen to them BEFORE they get in the incubator. If they were fertile then they could have gotten chilled before you received them. Or they may have been handled roughly which would detach the blastoderrm from the yolk. The egg would then have no chance to develop.

You still have plenty of time before school is out for the summer. Find some fresh hatching eggs from someone locally and try again. Hatching can be a wonderful learning experience for the kids.
