I have duck eggs that pipped yesterday morning but that's all the progress they've made as of right now. From pip to hatch, how long will they last? I'm concerned that the eggs are too small (these are really tiny duck eggs) and they won't be able to make it on their own. So... Not that I'm ready (AT ALL) to intervene, but if I have to... If they don't make any more progress... About how long from pip to zip and zip to hatch with ducks?
