out of the 10 eggs that I thought would be growing only 1 egg grew and had veins. this year my Silkie chicken hatched 3 eggs and 2 chicks lived (other 1 died we dont know why but we found it under the hen dead) and the eggs are from the same chicken, my porcelain d'uccle . the porcelain d'uccle is currently sitting on her own egg i removed the other 9 and put them under my silkie hen cause she got broody again . just so she will know she is sitting on eggs and not get worried. that other 1 egg was the only one with veins in it. on day 17 it had tons of movement, but day 21 none at all or maybe i just can't see it. i candled it today and it was all shadow except the air sac and a little space above that and i could see a few veins connected to the air sac still. i was scared if it was gonna pip while i candled so i candled the whole egg in about 10 seconds and put it down (i tried not to be fast though) i'm worried the egg got too humid because every other egg had a huuuge air sac! but not this egg. just maybe it didn't show? so what should i do? i heard eggs can hatch until 24 days. i'm worried cause what if the egg is gonna hatch but it gets too humid and suffocates! should i put it in a cooler place because the chicken's skin is touching the egg so maybe too much warmth for the last days? i'm just so worried idk what to do!
