It is not easy to tell anything. I had to make a rescue mission on one of my bantys last week. I will add a pic you can see after I got half the shell off. There is a winging it method to it because each chick will need its own level of assistance, mine was weak and couldnt get out on its own because it was saran wrapped by the inner membrane. I had to slowly peel away the outer membrane and shell and dampen the inner membrane stretching it away from the chick without breaking any of the vessels. I got one of them accidently but it did not injure the chick, shes my little baby now. I suggest you get a good light source, damp towel, tweezer, cuticle scissors help but arent usually necessary, cup of warm water and qtips to help if your membrane starts to dry out and some damp paper towels. As far as whether or not it has absorbed the yolk, mine had not fully absorbed the blood or yolk but was in fact going to DIE if not helped. I wrapped (loosely) it in an old CLEAN damp burp rag and wrapped that again loosely in a heating pad on LOW after 45 min to an hour and a half the chick had absorbed everything and detached from the shell. so patience is key and a steady hand really helps too.
