I love byc a lot it should invent its own app. Either way I'll use the site and the calendar in my kitchen for egg tracking. Just gave my an idea to put one in the coop

**I used the egg tracker for a clutch of eggs I set a couple weeks ago. Unless I'm doing something wrong, there doesn't seem to be much to this feature after the first day. Jot down the number, size and weight of biggest and smallest only (which I couldn't do anyways as I don't have a scale), and that's about it. It'd be nice to be able to keep track of each egg (update size, weight, air cell changes..notes..remove eggs tossed out..). And keep track of "the day" rather than just show you what day you set them. Also reminders to candle on candling days (7,14,18). I haven't even touched the egg tracker since I set them. It's nice to know what day I set them incase I forget, but it'd be awesome to have it more interactive and helpful..
