I have a little bantam girl sitting on a clutch of 14 eggs (she hid the nest from me, and by the time I found it, she'd already had 12 eggs...), and I lost track of when she started sitting. I want to say it was the last week or so in January. I'm guessing it's been around 21-27 days. How long should I let her sit before giving up hope? Also, could I have the hatch date/s wrong? Oh, she won't let me get close to the nest to do a candling on the eggs. BTW: this is my first hatching ever, so I'm a bit clueless, and nervous too!
