My dad's muscovy hen has started laying eggs again. She's laid 5 so far (at a rate of 1 a day). Not sure when the first was laid. I ordered an incubator and want to incubate and hatch them. My questions are: can I leave them with her in the nest till it gets here? Also, how long after they're originally laid before incubating won't hatch them? Like I said there's 5 right now and i'm not sure when the first was laid, do I still have a good chance of hatching them?
