Julie,
It won't hurt anything...just do a search on this site for candling egg pics and you'll get tons of pictures...I don't do it too much...but it is a thrill to see a chick in there moving. You'll generally see a dark spot and red veining which indicates good growth. It helps me with the long wait to do a peek now and then to know things are progressing well!! I'm bad at waiting!!!
