Title: Humidity for hatching duck eggs
Post by: Helencus on March 02, 2012, 10:26:55 pm

Hi guys long time no speak! I'm just setting some duck eggs in my rcom suro 20 but every site I look at I get totally conflicting guidance on humidity levels. Can someone set me straight please. Cheers :)

Well I hatch them successfully at 55% during the incubation and 75% at hatching, in an Octagon 20. The trick is to candle them each week though and see that the air sac is growing as it should, adjusting if necessary.

Thanks I've got them in at 55%. How do I know if the air sac is as it should be? I've done hens eggs before and just left humidity until stop turning. Candles to see developing but that's it.

You're welcome  :) After a while you just get a feel for it, but I used these sorts of diagrams when I started, it gives you a rough idea  :)
