OK ive just completely abandoned the hygrometer, ive had it in since yesterday and it gave a stable reading of around 60% to 65% and that with 1 of 2 water chambers full, so im just gonna keep 1 water chamber full for first 25 days and im going to lightly spray the eggs daily and hope for the best, i just wasnt happy with leaving that hygrometer strapped to the roof because i just had a feeling it will fall and crack the eggs, anyway i just put them in now! I know it hasnt been 12 hours but meh i cant see that making a difference, they were only laid yesterday so they are fresh as can be and i did settle them for about 2 hours so im hoping thats enough, omg i hope this works!
