Mine are peeping! I can hear it when I am near by. Trying ever so hard to not peek, it is so hard. I really need to build a periscope so I can see in and all around though the vent hole. I guess my temp was alright since they are hatching on time. That is a big relief especially since this is my first time and I have no clue what I am doing! I know that my neighbors who lent me the incubator didn't know what they were doing at all and kept opening the door and then having to help chicks out of their shells, some of them were crippled and it was sad. I can see why that is hard though, after three weeks of waiting for chicks to hear them chirping without looking is darn near impossible! Somebody post pics so I can get a fix!
