    Hi,

    This might seem like a stupid question but what does 21 days for incubation actually mean? 21 full days, i.e. 21 24 hour periods? Or does the day of set count as day 1 and therefore 20 24 hour periods.

    If I set eggs at 9am on a Sunday, does this count as day 1, or is 9am on the Monday day 1?

    Thanks

    Day one ends 24 hours after you set them.

    Most eggs begin pipping on day 21 or slightly before.

    OK, I didn't see the first part of your reply. Now it is clear. Thanks.
