Hiya, I had 4 good looking eggs and 1 iffy one when I left the incubator in lock down and had to go away for a few days. Day 20 one chick hatched and was helped out of the egg by my partner. I wasn't here so couldn't say how long the incubator was open for or anything. Now it's day 22 and the other eggs don't look to be doing anything. I candled last night and couldn't see any movement or beaks into air sac. What's the most likely reason for my eggs giving up at the last minute? Would low humidity prevent them being able to get through into the air sac? I've read that humidity spikes when the first chick hatches - up or down? Would I be able to get a small enough humidity checker thing to go in my incubator? It's a Brinsea ECO. I don't plan to hatch anymore until next spring but will be planning to drop the temp a little, or stop the turning one day early. Does this sound like a good plan? The chick I have is lovely, but now it means I have 2 lone chicks from 2 hatches. I'll wait till the newest gets a bit bigger and then introduce them to each other so they'll have company. It's frustrating when things look to be going right and then just stop in the final stages and I really want to get to the bottom of it. I can't blame dud eggs this time around. Thanks in advance for suggestions.
