Thanks for welcoming me in BYC, my incubator is a River egg tech 49 it the same as the Borotto incubator, my temp for the first 18 days was 37.7 and then the manual said to reduce to 37.2 for last 3, the humidity is hard to keep above 60% it keeps dropping so I have to keep filling up with Luke warm water. One chick has finally hatched and there is another 5 piping. Any advice for me .
