I originally had a reptile hygrometer that I used. I ordered a Springfield on Day 1 of hatch, but never received it til day 16. It is now day 19 and the hygrometer that I've been using reads 50%-53% and the Springfield reads 39% & 100.8*. My other 2 thermometers I have in there say 99* & 102*. Im not quite sure which to go by. Im having a very hard time keeping my humidity up anyways. Im trying to keep it between 45%-55%. If I go by the reptile hygro, then Im fine, but if Im going by the Springfield, then Im still low. I am using an LG still air with silkie eggs. I have filled all the water wells up to the top, plus 2 bowls and a few small pcs of rag (because I didn't have a sponge. Im thinking the Springfield would be more accurate, but not sure. This is my first time hatching. I just found out how to accurately calibrate a hygrometer, but at this point, its too late, as I can't open the bator. Thanks for the advice and help!
