Hi All,
Since this is my first time with eggs, I had a few additional questions.

1. If the eggs are fertile, how long after laying should you see evidence of veins/embryo?

2. Does anyone have pictures of candled eggs at different points in the incubation period? After 1 week, 2 weeks, 3 weeks, 1 month, etc?

3. What is the difference, appearance-wise, between fertile and infertile eggs?

4. If initially fertile, how do you know that your egg has died?

I tried to look up some of this information on the internet and I didn't seem to have much luck. Thanks in advance for any help you can provide!

Hello! Hopefully others will chime in, my experience is limited to three clutchs of EBTs. The first egg I had were 5 years ago from a rescue female that year. They were layed the end of July and incubated artificially. Other than keeping them moist, I didn't candle them. One collapsed early. Of the two, one hatched and the other (which had 0 development) looked fine to me past where the other hatched. The hatchling is now an almost 5-year old, not quite mature male. Awesome.

I have a female someone gave me. Three years ago she layed eggs, although I didnt know her history. The clutch of six looked fine for most of two months, after they turned funny colors. There was no develoopment in them.

Last year I found a female EBT whose head had been crushed on a busy road. I felt eggs in her and opened her up. Of five eggs, one broke during he operation. I incubated the other four. At about a month, we "candled" the eggs and could see veins and a moving embryo in the two eggs checked. I only checked the two eggs the one time. Of the four, one was infertile. One died at hatching, and I have two yearling right now!!
