I did a quick search and could not find exactly what I'm looking for. I ordered some Ebay eggs from some sellers I saw had good reviews on Facebook. BUT I forgot about the mail holiday. I have some large fowl Welsummers (12) arriving tomorrow the 20th, d'Anvers (12) arriving on Jan 24th and bantam cochins (8) on Jan 26th. Hopefully they arrive sooner but these things happen. Since bantams tend to hatch at day 19 I feel safe putting the Welsummers in earlier than the others. So here is the question - when I add the bantam eggs to an already running incubator do I add them all at once or a few at a time? I'm leaning toward the all at once and just dip the temp once.
