I can see the heart beat at day 4, I have some on day 8 right now too...and they arent moving around the egg so much yet- But you sure can see them in the middle middle of the network of veins they kind of move their little tails around a bit. My biggest embryo is already nearly a centimetre long already!! I can clearly see the eye - aas its the black dot up one end- they sure do grow out of proportion to begin with.
Thanks! I was so geeked to know I have at least 3 alive ones. I have been having such a hard time with my incubator keeping a regulated temp for some reason. It is a miracle they have made it this far.
Good luck with your eggs as well.
I have been running mine almost constanly since August last year - I had a few issues in the beginning- but have prety much tweeked things to how I think works best. There are so many variables - but sometimes when you least expect it...An egg you think has died- pips and you remember that all the stress and worry really is worth it.
