I'm new to this world of incubation. This is my first time. I've done everything in preparation for incubating chicken eggs. OK, it's day 21. Nothing, no external pipping & I don't know if there's been internal pipping.Moments before lock down, I candled the eggs & they were very much alive. Air sack seemed to be correct in size & angle. The only problem I can see is, the eggs are in an LG & I'm getting frustrated with the, in my opinion, temperature & humidity readings. I have a thermometer & humidity gauge in the incubator because the digital read out of the LG is way different than the reading of the thermometer & humidity gauge. I didn't find this out until a few days before lock down. I wonder if the chicks are still alive at this point. I'd appreciate all help with this. Thanks! In advance.
