I am new to having a hen hatch eggs. One egg hatched on its own on day 20. Today is day 21 and the chick peep yesterday and had a tiny opening first thing in the morning. No improvement since. I don't want to interfere just yet, but could use advice? I pulled a very small amount of shell by where it peeped and I could see it moving and it started peeping a lot! so I put i back under the hen. How long could this take and how many hrs till I should be concern? I just want the absorbing to go right as well and don't want to kill the chick.
