Hello. So I am on day 19 of my hatch and everything has gone good up until now. I am hatching black copper maran eggs and this darn incubator will not stay at 70% humidity. I have read the directions and suggestions repeatedly and even had other people look it over and we seem to have done everything right. my question is are there any tricks I can use to bring the humidity up? It is staying around 60% is that sufficient? the incubator I have is "Impeckables SKU#2293825" in case anyone is wondering.
