Hey this is my 4th hatch and as i do more my results are getting better but im having alot of trouble controlling the humidity. I will attached a photo of my incubater. I have a hygrometer inside and it controls temp itself. I have no idea how much water to add so ive just started a little at a time but the humidity is constantly spiking to 65 and the dropping to 20 and it dosnt matter how little water i put in or how frequent it seems to just do its own thing. I have no manual for this incubater. Has anyone got any advice. I did caliberate my hygrometer with the salt test.
