When should I give up on an egg?

[newwestchick]

I have a broody who has successfully hatched two of the three eggs under her, one pipped Friday and hatched Saturday, then yesterday morning we had a second appear. The third egg is not pipping or chirping, but she is still sitting on it. I'm wondering how long I should let it go before I take it away as being a "dud"?

Sunday, yesterday was the 21st day. All were started on the same day. She is being quite insistent on staying planted over that last egg, and the two hatched chicks have feed and water nearby and are happily eating drinking and chirping away.

Thanks!

Anyone? I can't seem to find any info when I search the forums... Thanks!

The hen usually figures it out. She will get off the nest and not return. No reason to not wait until 23-24 days.
