I have a broody and i don't think she kept the humidity of the egg at a healthy point because the chick broke some shell off, but cant break the membrane, I can see her pushing up on it, but it is not breaking. I put a drop of water on it and you could see through to her but She can''t get out of the egg! Help! It is a bantam at day 21 by the way.
It does take a while for a chicks to hatch, here's a link to assisted chick hatching that might help: https://www.backyardchickens.com/a/step-by-step-guide-to-assisted-hatching
