Mum's incubating 3 duck eggs!

Today I got my mini incubator. Seems all I have to do is top it up with water every 4-5 days and the machine does the rest (timing/turning).

Put my 3 "best eggs" into it, programmed it and now ... the count-down begins! I've set it to "duck" eggs (obviously!) and it has automatically calculated 28 days ... which I think is correct for khaki campbells?

The box the incubator came in doubles as a brooder pen for the first two weeks (if I so choose, but I don't) I will set up my own brooder pen.

Never used an incubator before, so this is all new-learn-as-I-go live action

Wish me luck!

Any and all suggestions for hatch day, duly welcome!
