At what point (day) do you consider the egg unviable, undeveloped.
Day 3 we had a bunch developing. Day 5 (today) i see veining on many, but im not expecting all 41 to hatch..... Just want to know when i should consider the others duds.
i would say way before day 10 you should know but i keep them in that long just to be extra safe and hopefull
here is what the chicks should look like inside the egg day by day
by day five you should see movement inside the egg when candles and really strong thick vains.
