silkie chicken incubation period?

[broodysilkies!?!]

I have a broody sitting on three eggs that were due on 1-1-12 and today is 1-5-12 and NO CHICKS IN SIGHT!

Temps have dropped into the 20 yesterday! (in Florida imagine that)



WHAT IS WRONG WITH THEM?
&
WHAT DO I DO NOW?

thanks in advance

ALL SUGGESTIONS AND COMMENTS WELCOME!!!!!!

Have you candled any of them?

I would candle or float test them just to be safe but I have had some eggs hatch on day 27.

have candled and they look good but they seem to be moving....

NO PEEP HOLES THOUGH
