Hey all my hen is incubating for first time. Today day 20 the egg has a crack just a little in the top but the membrane still intact. I place the egg under a flash light and I can see that th3 chick is breathing fast if I saw correctly. Can you guys please let me know what to do. The crack was this morning about 6 am and is now 7:30 pm. I think I heard a peep but not sure
