I'm on day 25 of incubating a goose egg. I had seen a air sac last week. Now I don't. I see lots of movement but no distinct air sac. I use a humidity dial. Not digital. Tried to keep it at 50-55 humidity most of the time. It spiked up three days ago and I had to take water out. Does this mean the baby goose is going to drown? I was going to raise humidity Friday. What do I do? I also have been tilting the egg pointed side down... Spraying daily and turning often. 99.5% temp. Help please?!
