What are the odds........

[Chickiechick]

Well I decided to seperate out the coturnix with the plan being to set up 2 or 3 breeding groups. So I start picking out the jumbos ...... ok, roo, roo, roo, roo

8 jumbos, 7 are roos

Ok change of plan. 7 roos now "growing" for one or two more weeks. The largest will get a girlfriend. The others , well a BBQ sounds good

Lets hope there are some hens in the A&M's & Tuxes.
There are 2 goldens and a tibetan too so I'm off to check the coturnix sticky about sexing them ( please send hen vibes my way

)

First, want my recipie for stuffed quail?

Second I read a few studies (I can dig them back outta proquest if you'd like), that discussed high mortality of female embrios if there was a heat spike late in the incubation. My first hatch had a heat spike of 112-117 the day before hatch and the eggs that did hatch were all boys, the non-pipped eggs I checked were girls (vent sexed them). Could you have had a malfunction during incubation?

Added note, vent sexing dead chicks is not pleasent, but when the 9 hatched were all male, I suspected the heat spike deaths.

what if there was a heat spike of 105 2 days after setting them? the reason i ask was that it happened to me

im on day 3 now

That early you should be ok, it seems the last 2-3 days of hatching lead to the killing of female embrios, but there's not yet a conclusion on why it happens, just that it does.

 

[Chickiechick]

2 goldens = 2 roos
2 tibetans = 1 roo , 1 hen

That just leaves the A&Ms & Tux's to come to the rescue for egg layers.

Saddina - Yes a stuffed quail recipe would be great. There's going to be a whole lot of stuffing going on over here.

No known temp spikes during incubation but that is an intresting theory. Is it just coturnix ? I hatched a bunch of buttons in the same incubator at the same time and best as I can tell right now it looks to be 60% roos . A much better gender mix than those

coturnix

It's documented in chickens as well.

Interesting read..

I will keep an eye on my bator temps next time. I got lots of roos too.. But I had a female Button Quail sit on her own eggs. I know the temps didnt get high there. She got off her nest alot. She had 4 roos.

Maybe I should run my bator a little cool one time. And a bit warmer the next time and see if there is much of a difference..

Does any one know of any links to any studies about high temps killing off girl embryos..

I had to dig back thru 60 some pages to find this one...

Very end talks about the diferance in orgen development in male vs female hatched embryos (the chicks were gasses and dissected)

http://ps.fass.org/cgi/content/full/86/12/2685

Most of the ones I had were proquest and you need an acct to link into more than the abstracts.

I feel your pain...I have 4 birds right now and from what I can tell with the vent sexing, 3 of the 4 are roos

So I am planning on getting more birds...but OY what a predicament in the meantime...only one poor little pullet in the bunch.

Good luck with getting some more gals!
