I'm thinking something wasn't quite right during incubation. I set 21 duck eggs from my ducks, had 100% fertility, I didn't see movement in all of them when I went into lockdown but quite a few were moving and I was doing fast candles, didn't want to mess with them to much. So far 1 has hatched, 1 is almost done hatching, and 2 more are pipped. With those crappy percentages something probably happened.
I know that earlier on my electricity went out multiple times a day, for a couple of days in a row (electric company was working on the system and failed to mention it ahead of time

) so maybe that had something to do with it? Although I also set a bunch of eggs from my layer flock, and those are steadily hatching, have to check but I think over 50% have hatched so far.
I do have some shipped eggs in the bator also, Rhodebar. I don't know if I'll ever do shipped eggs again, I bought 12, they were packed so some were near the edge of the box and one was smashed on arrival. 4 more never started and I saw no bulls eye when I broke them open (yolks were intact), 2 of the remaining fertile ones I'm pretty sure were pullet eggs. 1 has hatched so far, and when I candled tonight I saw no movement from the other 6. I think I have a $40 Rhodebar Rooster
