hi, so I candled my eggs today in the morning to see if anything different is happening and if the chicks are alive. I already put them on lockdown. Egg nr. 1 is a light brown you can see through it pretty well and the air sac was getting so much bigger and so was the chick nothing weird happening with this one. Egg nr. 2 the chick was moving here quite a lot but it seemed to me like the air sac did not change since day 17 and there was space left you could see the vitellus. Is that a bad sign? Egg nr. 3 was also doing fine. Please help!
