Also i use one of the small indoor/outdoor weather type stations that tells indoor and outdoor temp and humidity its gotta digital screen just stick the small sensor in the bator and youll have pretty accurate readings. Pick it up at wallword for about 12 bucks.
Yeah looks right i candled a few of mine when i hatches some air cell was same place as those. I would add a little water at a time to try and get humidity to 40%. I have a forced air farm innovation 4200 i kept my humidity between 40-50% when they started hatching the humidity went up by itself...
