Since it was so late last night when they went into lockdown, I only did a cursory check of them, placing them air cell side up, but was more thorough this morning.
Several internal pips from the ducks. All have received a small pinprick breathing hole. Chicken eggs look good, but I didn't see any internal pips yet. Then again, they take much less time than ducklings to hatch.
I'm surprised the OEGB/Silkie eggs didn't develop faster.
Next week, I'm off to the livestock sale with bunches of chicks! Unsure how many ducklings will go though. I don't get attached to chicks as much as ducklings. And since my Magpie drake is probably fox poop at this point, I'll need to keep any Magpie-marked ducklings to try to figure out if any are purebred.
