They look like they are doing good. I would give them a few hours if there's no progress, I would pull small pieces of the egg off at a time. Peel the egg from the membrane first and then check the membrane to see if there are any blood vessels still. If so leave it for a few more hours for the blood to soak into the chick. A little bleeding is normal.
These eggs have been pipped since this morning. This is my first time through this, and I swore up and down I would not brood any more chicks- would let the broody do it. *sigh* Well, now the broody has gone off the deep end. I honestly think she was sick of the whole process; she was happily out with the flock after I took the eggs.
