I don't think there would be development.
I candled tonight in pitch blackness except for my candling light. My eggs are all light cream to pale brown. I can tell you it is very hard to see in the darker brown eggs.
I would not get upset if you can't see in the eggs if they are brown or very thick shells at this point. I'm on Day 7. I had my DH take pics and I posted them in their own thread a few hours ago. I'm homeschooling too so of course my daughter had to come participate even though she was exhausted from working on the fence line for the new North West Pasture after church today. She perked up when we could see veining. I didn't take out any of the eggs that didn't look developed as 7 days is still early and I'm not experienced at this at all.
I believe that 2, 3 and 10 are no good, with 2 of them being clear and one a blood ring. However, I'm not positive about that.
Just wait a few more days and candle again. Keep your nose checking for stinkies.
I think as a Homeschooler it's important that they learn the whole lesson. They have to know that there is loss in this endeavor, and that we as adults can make mistakes just as they as children do. If we present ourselves as infallible then they will feel the need to be perfectionists as well. So I'll be seeing this through to the end, and if we only get 2 out of 11, or 1 out of 11, or none, I'll do it knowing I've done my best. That is the best thing I can do for her.
I have a favorite saying that might help you deal with this one. It's slightly religious but you don't have to take it that way.
I am careful not to confuse excellence with perfection. Excellence, I can reach for; perfection is God's business.
Michael J. Fox (1961 - )
I say this to myself every time something happens that I can't deal with and in my need to have perfection, or be perfect I try to control the situation. So, the temp spiked, you have no idea why it was out of your control. This hatch isn't going to be perfect. What's important is the process and that the kids learn about it. What chicks you get will be adorable.
