Hi - I am getting ready to lockdown as you all say (this is my first time) and I am pretty sure that due to temp variations that not many of eggs will hatch. Which will make me real sad! If someone has some pictures of what an egg candled at days 17 or 18 should look like will you please attach? I realize the chick should take up most of the egg. I really can't tell on the green eggs what is going on but on the white ones I just see an air sac and a somewhat large dark circle but no eye, veins or movement. Still I don't understand how the darkish circle is getting bigger. But believe me my hopes are not up! Thank you for your help. I really appreciate your expertise and feedback. This is so stressful!!!
