Air sacs too small-- how much to reduce humidity?

[Brickman House]

Hi all,

I'm on Day 14 with 16 chicken eggs. I've been running the humidity in my Suro at 50%. Candled last night, and the air sacs are really small-- more like a 7 day egg than a 14.

Anyone had experience with this, and how much did you reduce humidity to enlarge the air sac?

Thanks!

I would personally run it at around 35 for about 4 days and then candle again. The good news is that humidity/air cell development is basically taken on an average over the 18 days before lockdown, so it's great that you caught this early. BEST of luck!

Oops - ETA, I just re-read that you're already on day 14....I would then run it at 30 until lockdown. If you don't get enough dry-down, the chicks have the possibility of drowning, and you only have a few more days to reduce it.

Agree with Wynette. I adjust my humidity by the aircell size in my Suro too. I candle at 7, 14 and 18 and adjust accordingly.

Thanks for the info-- I'll drop it down to 30.

Like you, Oldtimgator, I candle at 7/14/18 days as well. They looked fine at 7 days, but just haven't seemed to shrink since. Hopefully the drop in humidity will get them where they need to be this week.

You might consider the weight loss method next time; you really can't go wrong that way. I've had my best hatches using that method. BEST of luck on your hatch!
