I know we are not suppose to open the bator after lockdown, but I am really having trouble keeping the humidity above 60% in my Hovabator 1602N. Is it okay to open the bator if none of the chicks have pipped yet, it is day 19 and I am really sruggling to keep it up.(I have opened it today to add water, quickly) Any suggestions, all wells are full and I have a sponge in it too. Not sure what to do, will the chicks be okay?
