I have hatched tons of silkie eggs in my incubator and they all have been shipped to me. Yes, I have had any and every single kind of problem you could possible think of, exspecially the air cells. I just had 32 eggs shipped to me and 8 of them have loose air cells. The rest seem to be pretty good. All of my silkies have hatched a day or two late never on time. Most of the problem with my silkies is once they are hatched they seem to develop leg problems and i usually have to tie them up and within a matter of a day the problem is resolved.. I have hatched out other kinds and have to agree silkies are a little more difficult.
