Thanks for the advice - humidity the last few days has been about 65% but as soon as First born shot up to about 75% and now its at the 60% mark. Think I'll wait till bed time and have another look . Ive the brooder box ready and the brinsea hen is warmed up ready I may top up and move her over then...it is really up to you. Some will say leave that chick in there and never to open the incubator til the hatch is finished. Me personally I have a brooder ready and move the chick once it's most of the way fluffy and add more warm/hot water in the incubator. I've never had any issues doing that. Although 60% humidity is all I keep it at for the hatch.
