Confused about humidity levels (Incubation & Brooding)

by domerdoc, Sunday, April 16, 2017, 09:36 (14 days ago)

I've owned guineas before but I'm incubating them for the first time. I've read in various places that 50% humidity is ideal and other places say 65% is ideal until day 25. And yet I've read that dry incubating is very successful. I have a forced air Brinsea 20 with a humidity pump so I can be very accurate with the temperature and RH levels. My problem is that I can't find consistent information about the humidity level. Can anyone please help me with the humidity level please?

According to Jane Smith...

by Barbara-NH, Sunday, April 16, 2017, 14:32 (14 days ago) @ domerdoc Section 11 of her article found on this website and titled "Setting Up Your Incubator":

" should aim to run your incubator at about 55-60% humidity from setting until internal pip, and then crank it up pretty high for hatching..."

Jane's advice fits right in the middle of the recommendations you've seen elsewhere. I've never incubated guinea fowl eggs, so I can't offer any first-hand advice, but that seems like a sensible approach to me. I'm going to ask some of our members who post on our Facebook group page to offer their opinions on humidity levels for successful hatching. Hopefully, you'll get a few more knowledgeable replies to your post before too long.

I hatch about 2500 a year with an inconsistent 45 to 55% [image]

I usually try to maintain 55 per cent until day 25 then I kick it up to 75%. If it is too high in the beginning, it is possible to drown the keets. YIKES!!

Good luck.

"I live in a dry climate. If you live in a dry climate, dry incubation is not recommended. I raised turkeys before I raised guinea. Porters Rare Turkeys has some good hatching advise I think also applies to guinea other than the days. My incubator is preset. I hatch all my eggs the same. Chickens Ducks, geese and guinea. Many times at the same time."

That web site does a good job of how to hatch eggs I think
