Planning to hatch eggs? Candling lets you peek inside to monitor development without cracking them open.
What IS Candling? Shining a bright light through an egg to see internal development. The egg becomes translucent, revealing what's happening inside!
When to Candle:
🥚Day 7-10: Check for development and blood vessels
🥚Day 14-18: Assess growth and air cell size
🥚Day 18+: STOP handling eggs (lockdown period)
What You're Looking For:
FERTILE & DEVELOPING:
🐥Spider-like blood vessels (Day 7)
🐥Dark mass (embryo) growing larger
🐥Movement in later stages
🐥 Expanding air cell at blunt end
INFERTILE (Clear):
🥚Egg looks clear throughout
🥚Only yolk shadow visible
🥚No blood vessels or development
EARLY DEATH (Blood Ring):
☠️Red ring visible inside egg
☠️Development stopped
☠️Remove from incubator
Equipment: A simple LED flashlight works! Or purchase a dedicated egg candler. Dark room = better visibility.
Critical Tips:
🧼Handle eggs gently, wash hands first
😓Don't candle too frequently (stresses developing embryo)
🌡️Room temperature eggs candle more clearly
✔️Mark questionable eggs, recheck in 3-4 days
Fun Fact: You can see the chick moving inside around Day 14-16! The air cell also grows as the chick develops and needs more oxygen.
Your turn:
❓Ever candled an egg and been totally amazed (or totally confused) by what you saw? 🤔
I'd love if you showed your awesome candling video!
