When will my Muscovy duck eggs hatch

[rmc88]

Hi I Re homed two ducks from my cousin a female Muscovy and a male which I'm not sure of the breed any way once settled they did the deed and my female escaped her fenced off bit regularly but was always waiting to go back in the morning I found the reason for this is she had started laying eggs in a nest under my pine tree we noticed 7 eggs on the 15th of may by the 20th she started sitting on them longer. But wasn't till around the 25th that she's was on them pretty much all the time except to feed and have a little swim I assumed by the 25th of June we'd have babies but no sign I did a float test Sunday the 6th of July and there was maybe 5-10% above water can anyone advise when they might hatch ?

Pure scovies take 35 on average, so you don't know what breed the drake was? muscovy mating with mallard derived birds create infertile young(just an fyi) i would bet the incubation period would fall somewhere in between a muscovy and a mallard derived.

Have you candled the eggs?(get a super bright light, we use iphones lol) to see if their is veining or progress in the eggs.

Yeah we candled them around the 25th of June you could clearly see the air sack and the dark bit where the baby was
