Yesterday one chick hatched out at 21 days and today another one hatched out. There's one egg that's had a little hole in it all day, with not much progress, and one egg that we discovered out from underneath her and cold. She's still sitting on 2 eggs. My questions are: 1) How many days after 21 days do you leave before you/mother hen decides that it's a lost cause? 2) If the egg has been left to go cold does that mean that she knows it's not viable, or should we keep it warm ourselves? 3) Does she have to be sitting on the egg for it to hatch, or once the chick starts breaking the shell does it not matter if she's no longer sitting on it? The new chicks don't appear to be eating (unless they do so when we're not around). We've left chick crumbs and water where they can get to them. Will they just eventually work out what they're mean to be doing? There are some tiny poops so I assume that something has gone through their system! Thanks for any advice... we're new to all this!
