I have a chicken egg, and I got it from a biology class so im not sure when it started its incubation, but if i assume correctly today is day 20. There is no pipping, and im worried, when i candled my egg last night the air pocket was really big, but yesterday it started wiggling a little and then last night I could hear it peeping thru the shell. Im concerned that it does not have high enough humidity to hatch, because i dont have a closed incubator. (It was from a biology lab and I am a college student that cant afford an incubator). On that note im not completely stupid I bought a little thermometer and i have kept the temp very consistent at about 100 F, but i dont know about the humidity. Should I be really concerned?? PLEASE HELP!!!
