I have a few Call duck eggs in lockdown right now. They're supposed to be pretty high quality Calls, so I'm guessing they'll have a hard time hatching with their little bills. I have one that is internally pipped at the moment. It hasn't been for long, so right now I'm not concerned, but at what point should I help if it needs it? I've assisted with several hatches before, but all of them had already pipped externally.
