I know that I need to leave the egg alone, and I am I have not opened the bator, but last night at this time it was chirping up a storm, and I have not heard any chirping for quite some time today. Is it possible that it is just sleeping?? If not what should I do, Im not sure what day of incubation this is exactly but I know it is around 21 give or take a day. How long should I wait for it to make noise again??
