Thank you so much for this information! I just had my first hatch 10 days ago, and the last two chicks just could not get out of their shells, even though they had pipped all the way around. I finally pulled the shell apart just enough for them to get out. The last one was the biggest chick, and some of the membrane was dried on it's back like super glue. I tried to sponge it off, and finally after a week, she has new feathers or either the "glue" is finally gone. Even though she (i hope it's a she) was the largest, she is not the runt and very spoiled. She watches TV with me every night, nestled under my chin, and even tries to get under my cat like she would her Mama's feathers. I was so amazed watching these little guys come into the world. Thank you again for the lesson!
