incubating time

[perefalcon]

when incubating at 84 what sex can I expect? How many days till it hatches if it is fertile? How soon can I tell if it's fertile?

Sorry for so many questions I'm slightly bouncy right now :willy_nil :nuts: :spinny: :crazy03:

VEINS IT HAS VEINS!!!!!!!!!!!!!!!!

my first egg is fertile!!!!!!!!!!!!!!!!!!!!!!!

At 84 degrees the sex could go either way. It could be male or female.

Yeah at 84 there is a 50/50 chance on the sex and it should hatch between 37 and 60 days. Mine at 90 hatch at 37-40 days and at 82 they take right at 60-63. Ive never done any at 84 but it should be somewhere inbetween.

@ 84 you will not have 50/50 male/female ratio, please show me where you have proof on that. I know Alberto incubates some of his albino lines @ 86 and gets I beleive 25% males. I suggested to her that she set the incubator alittle above 82 as in my case my incubators ambient temp is 2 degrees warmer than the eggs are but I have temp gun and check the temps daily it may or may not be like that for her or others in either case @ 84 she will have mostly females.

Oh BTW I have personally incubated eggs @ 83-84 for 2 years now and can account for only 1-2 males hatching from those temps of over 120 hatched eggs.

Hmm, I'd have to agree with Xavier on this. I didn't notice any obvious sex ratio changes for males until I incubated at 86-88F. 90F sounds a bit too risky to me. At least at 88 if your incubator goes over by a degree or two you're still within safe limits.

There are lots of references out there for temperature sex determination, that is, if anybody likes to read scientific literature. For an easier read, I suggest going to the library and borrowing the book FireFly Encyclopedia of Reptiles and Amphibians by Halliday and Adler (2002). Pages 116-117 have an excellent description of temperature sex determination (TSD).

Well after 2 and a half weeks you can raise the temp to get a nicer looking female. Just my tid bit...

I incubated my last 2 eggs that hatched out last fall at 84 degrees, thought they were both girls until last night, one is definately a boy. All my others were incubated lower and all are females.

[dragonflyreptiles]

I incubated at 82 last year for all females and wound up with several males it was around 10% males. If I am not going to raise my male percentage by going up to Ill raise the temps!

[ZenReptiles]

What is the temps to avoid? Like when do you defintely get hot females?

I'm sure many will argee with me on this but 10% males from 82 degrees is not the norm. How often do you ckeck your temps maybe there is a discrepancy in your incubator and it flucutated to mid 80s. I don't think that firts website you listed is very credable I skimmed thru it found couple things I disagree.

You can get females and males from any range of temps in concern with the so called "hot" females came from male temps 88-90 shouldn't be too common do and I won't want to not incuabte for males just to avoid that, I personally have incubated only 2 females from male temps and have one which I purchased which was incubated as male but is female. Not sure how folks feel on it butt Ron Tremper states that females from higher temps take longer to become sexually mature and not that they aren't able to breed just aren't receptive at the same size as a normal female would be. So he feels there isn't really hot females.

At 84 you should produce mainly females, but most likely a few males too.

I incubate my female eggs at 82, male eggs at 90. I am about to set up an 86 degree incubator also, for all my Tremper Albino eggs, so the females won't be doo doo brown but I won't have to use the Tremper Method.
