I made an incubator out of a styrofoam cooler.With that being said the temp, was really had to keep constant.Now saturday was the 21 day so sunday night I thought my to eggs were not going to hatch and when I went to take the egg out it was really heavy.I cracked it open and there was a chick in it.He was alive and moving."By the way I felt really horrible"As I was checking him out his stomach did'nt look developed.My question is why after 23 days did I have a under developed chick.Should I have just left the eggs in there a couple days extra.
