Its day 21 of me putting in 12 chicken eggs, we put them in on April 6th on a Tuesday and today is April 27th and so far there's no pipping or chips and im very worried, we saw a couple chicks breathing inside the egg on around day 16-17 so we know they might be alive but so far its been dead silent in the incubator, my humidity is 70-71% and my temp is 32.5 C, please help, its my first time
