Re: I am incubating an egg w/something in it but not moving.

At an early stage of development the baby's heart will start beating so you 
might be able to detect the embryonic heartbeat. Perhaps a stethescope might 
be useful for this. Another way of detecting growth would be to hold the egg 
in front of a bright light and look to see if the yolk sac is getting 
smaller. As the bird develops the nutrients in the yolk are used up, causing 
the yolk to shrink. As far as any movement is concerned the young bird would 
be pretty far along (perhaps a week to a few days before hatching) before 
any detectable movement would occur.
