Egg records: weighing, weight loss, candling and pip dates

For breeders who weigh eggs through incubation:

• Mark each egg with the label you pencil on the shell.
• Weigh eggs one by one: the app tells you which egg is next, by its label, and shows how many are left today.
• Weight-loss line for every egg, measured against the usual 15% target to pip, so you see early if an egg is losing too fast or too slow.
• Plausibility check: if a weight looks wrong (heavier than last time, or far off), the app asks before saving.
• Candling log and pip dates, plus a daily reminder when eggs are due to be weighed.
