I've been hatching for over a month now and I can't figure out what is wrong. I put 3 dozen eggs into my bator three weeks ago. I tossed four that didn't develop at all after two weeks and left the others for a bit longer. On day 19 (yes, i lost track of dates, so it was later than it should have been) I candled the 32 left, twelve of which died sometime during the second week. Twenty looked reasonably well developed.
I don't know if the other 15 died before I candled the last time, or after, but to have that many that developed to such a late stage and then die? I can't figure out what I'm doing wrong. The temps and humidity have stayed pretty steadily in the right range with few exceptions (I have three bators, I start them in the LG since it has trouble with humidity).
Can humidity fluctuations early in the incubation cause problems later? I'm trying to hatch them for sale, in the hopes that I'll make enough to pay for their feed, but I don't dare sell hatching eggs, or put much hopes on paying for feed if I can't get a decent hatch. My first two were much better numbers than the last two bunches.
Chickens, ducks, geese, turkeys and guineas! I think I'm addicted to hatching.
