I am a first timer with our incubator and hatching eggs and have a question. When we candled tonight we saw several eggs with a dark spot with vessels spider webbing from them. My question is on the ones we couldn't see this we had several where the dark area got significantly bigger. Does this indicate a growing embryo? We had about 9 out of 35 that were unchanged and I assume are not fertile. It was interesting to see the rate of bad eggs in the great packaged eggs versus the okay packaged eggs. Most of our eggs are amerucuana but we put a few of our own fertile eggs in as well, Thanks for any replies.
