Hi all,

I built Hatch Day, an Android app where you set a clutch and it shows what the eggs need that day. But I'm a developer, not a poultry farmer so I need feedback from target audience.

What it does:

- Day counter and countdown for each clutch

- Today's temperature and humidity targets (°C or °F)

- Turning reminders at times you pick, and when to stop turning

- Candling days, lockdown and the hatch window on one timeline

- Cooling and misting days for waterfowl

- 11 species built in (chicken, duck, Muscovy, goose, turkey, Coturnix, bobwhite, guinea, pheasant, partridge, peafowl) plus a custom profile

- Works offline, no account

The free version tracks one hatch at a time. Pro adds multiple incubators, a candling log, temp/humidity logging and hatch-rate stats.

Most hatching charts assume chickens: 21 days, done. Muscovies (35 days), geese, and bobwhite vs Coturnix quail each have their own schedule, and that usually means digging through university extension PDFs. The targets come from incubator makers and university poultry guides. Your incubator's manual and a calibrated thermometer still come first.

What I'd really like to hear:

1. For those of you hatching waterfowl or game birds: do the humidity and lockdown numbers match what has worked for you?

2. Is there a species or step I'm missing?

I'll answer questions in the comments, and I'm happy to fix anything that's wrong.

Male layer chicks are born into a system that has no use for them.

Because they cannot lay eggs, millions are killed shortly after hatching. Some are ground up alive in industrial macerators. Others are suffocated.

They are born. They suffer. They die.

All because they are male. 💔

This is the reality of the egg industry.
