## What is Candling Day?

Candling Day is a hatch log for people who set eggs under a broody hen or in a small tabletop incubator: a family trying its first spring hatch, a 4-H leader, a teacher running a hatch in the classroom.

Open it next to the incubator and today's batch is already there. You see the day count ("Day 9 of 21"), the temperature and humidity targets for the current stage, how many times you've turned the eggs today (at least three, always an odd number) and what comes next: a candling night, lockdown or hatch day.

Log temperature and humidity readings as you take them. Each one is saved with its time and plotted against the target band, and readings that drift out of range show up straight away.

The egg tray shows every egg as a numbered oval, matching the numbers you pencil on the shells. Tap an egg to record a candling result (developing, clear, blood ring, early quitter or late quitter) with a note and an optional photo. Or candle the whole tray egg by egg in one quick session. A candling guide with drawings shows what each result looks like around day 7, at days 10 to 14 and at lockdown.

On hatch day, note pip, zip and hatch times for each egg. When the batch is done, close it out. The hatch record keeps eggs set, fertile and hatched, hatch-of-set and hatch-of-fertile, pip-to-zip times and your notes, and compares batches and incubators across the season. When you set the next batch, Candling Day shows how the last one in that incubator went.

Species covered: chicken, bantam, duck, Muscovy duck, goose, turkey, guinea fowl and Coturnix quail, each with incubation length, lockdown day, candling nights and humidity phases. There is also advice on storing eggs before you set them.

A reading shelf opens extension-service and poultry-club pages inside the app. Reminders for turning, candling and lockdown are optional local notifications.

Everything works offline and stays on your phone: no account, no ads, no tracking. The figures are general guidance only. Your incubator's manual comes first, and the app gives no veterinary or chick-health advice.
