Day 5 of Incubation

[Kessel23]

I use my phone flashlight to candle the eggs, I usually first candle them on day 8-10. Make sure to candle them in a dark room.

I know it's recommended to wait til day 7-8 but I usually candle first at day four and it is very obvious which eggs are developing in light coloured eggs. Photos of these five day old eggs being candles would be great of possible!
