I have read people say things like "I wait X # of hours after pipping before I help and X # after zipping before I help". That's easy when you have only a handful, but on large batches how do you keep it straight to know who's done what when so you can keep track? Or are you just not that organized about it? I have some small dry erase boards and I am thinking from now on I should number the eggs at lockdown, and then I can write notes about each on the dry erase. I'm just seeing if anyone else has a different approach that might work better. I can be quite a data geek so may even end up doing it all using excel and numbering them when I set and making notes throughout the incubation. My real goal is to get good enough at it to produce reliable results, not so much for my ego but because I feel like I owe it to these lives that I have perpetuated.
