Hello! I just joined today! I am incubating 18 chicken eggs. I put them in lock down on the 18th day,all were alive.On the 21st day in the afternoon two pipped,one hatched at 3 a.m. the next morning, the other one had made some progress,but not much. BY noon it had pipped halfway around and stopped making progress. in the afternoon it was the same, it was all dried and stuck to it's shell,it was taken out of its shell.why was it stuck to its shell?. Its the 22nd day and only four have hatched. they are ADORABLE!,but I don't know why the others haven't two of them had belly-button problems one was worse than the other,it's umbilical cord was attached to a weird whitish thing so we snipped it of (we left a third of an inch) and sprayed blue-coat on it. Any ideas on why their hatching late with not fully healed navels?
