Candling experts - Yolk Location/Behavior

[enggass]

When candling on day 5, will the yolk/embryo object still be able to appear to float freely from one end of the egg to the other? For example, if you canlde the small end, then rotate the egg 180 degrees and candle the large end is it possible for the yolk/embryo combo to slowly float to the opposing end? Or would they be stationary and attached to the shell via blood vessels at this point?

With my experience it still floated around unless it was attached to the side of the shell due to me not turning them properly. Around 7 days i think is when i notice that it doesnt float freely anymore.

Do the veins sometimes attach only to the yolk or do they always spider out to the side of the egg? I am talking day 5...
