First time hatcher here- I have a few questions....3 pekin duck eggs, only 2 are fertile. With a 28 day hatch for pekins how long should I wait to toss the one that I think is infertile? Also, it doesn't say anything about what to do with temp and humidity during "lockdown" with the chickubator incubator instructions. It does say not to turn them, but that is it. It didn't come with anything to monitor humidity, it only said to fill one of the legs with water. Should I add water to the other 2 legs to up humidity during lockdown? Also what do I do with the temp during lockdown? Last question...it seems super small for a duck to hatch in the chickubator, should I take them out during lockdown so they have more room (I have an old fishtank I can use instead and I have seen quite a few ppl on here are using them as incubators)? Thanks for all of your help! Such a great board!
