It’s day 16 and for some reason the humidity levels in the incubator are going nuts today. Started at 30 then I added water as usually do and it jumped to over 60, then dropped to 50 then 40 and 30 again. I added water and it jumped up to about 65. Settling now at 55 ish but I don’t understand why it’s doing this now when has been steady for the last weeks. I candled to check and the chick is doing great . Gave a big kick that showed a whole foot! The air cell seems good too. Should I be worried ? Never done this before. Only have one egg!
