Hatching question

[Lobzi]

How many days does it take for a full nest of say 11 eggs to hatch?
I know the exact starting time and day as mama was off the nest and I got to see the first pip!!

If your talking chickens its 21 days. You start on day one after mama had sat for 24 hours

No I mean the actual hatching process....all dont normally hatch at the same time do they? If so, she may only have the one survivor.
Yes, Im talking chickens. This is first time I have actually known the exact time the hatching started.

Found the answer I think at
http://www.thefarm.org/charities/i4at/lib2/chickens.htm

"Once the chicks start to hatch she will remain on the nest with them for 24-48 hours. Any eggs that have not hatched by then will be left behind when she takes the chicks for their first walk. At this time water and chick feed should be available for the chicks".
