I have two LG incubators and just hatched our first group of 4!! Well... 3 of them have hatched so far. They went into lockdown on 11/14 and were due to hatch tomorrow. I haven't had any problems with them yet. We have never hatched before so are very excited to have a 75% hatch rate so far... hoping for 100%
We have one LG with an egg turner in it for incubation. We do not have a fan. Humidity stayed around 30-40% and temp at 99-100. We even had the power go out for an unknown number of hours, and they still were fine. The temp dropped to 70s and the humidity jumped to 60% when that happened. I kept the plugs in the whole time because if I took them out the humidity would drop below 25%.
I did have a little trouble getting the humidity right for lockdown. I plugged in the second LG that we have a few days before lockdown to mess with the humidity. I ended up using a couple wash clothes rolled up with one end laying over the water channels at the bottom. That still didn't get it higher than 60%, so I found a couple small tupperware dish tops and put some water in there under the hardware cloth wire filled with water. That brought me up to 65-70% which has worked fine. Each egg that hatched the temp went up slightly and the humidity did as well. I kept the plugs in for lockdown too, but when the humidity went up passed 75% and the temp past 100 I would open them for about an hour.
So far I am happy with the LG despite what I have seen others say about it. For a first timer it has worked great!!
